Use the graph of the function to find the domain and range of f. (Enter your answer using interval notation.)
The domain and range of the functions are Domain: (-∞,∞),{x|x∈R} and Range: [4,∞),{y|y≥4}.
What is vertex form of a quadratic function of graph?The vertex form of a quadratic function is f(x) = a(x - h)² + k, where (h, k) is the vertex of the parabola. The coefficient a determines whether the graph of a quadratic function will open upwards or downwards.
From the graph, vertex is (h, k)=(0, 4) and (x, y)=(2, 0)
Here, y= a(x - h)² + k
0=a(2-0)+4
-4=2a
a=2
Substitute, a=2 and (h, k)=(0, 4) in y= a(x - h)² + k, we get
y=2(x-0)²+4
y=2x²+4
So, f(x)=2x²+4
Find the domain by finding where the function is defined. The range is the set of values that correspond with the domain.
Domain: (-∞,∞),{x|x∈R}
Range: [4,∞),{y|y≥4}
Now,
(a) f(-3)= 2(-3)²+4=18
(b) f(2)= 2(2)²+4=12
(c) f(0)= 2(0)²+4=4
(d) f(3)= 2(3)²+4=18
Therefore, the domain and range of the functions are Domain: (-∞,∞),{x|x∈R} and Range: [4,∞),{y|y≥4}.

Answer:
1. MAD for Jada's data set = 1
Step-by-step explanation:
Mean Absolute Deviation = sum of the distances of each data value from the mean ÷ number of data value
Jada's data set is given as: 4, 4, 4, 6, 6 ,6
Mean = 5
✔️Find the distance between each data value form the mean
4 = |4 - 5| = 1
4 = |4 - 5| = 1
4 = |4 - 5| = 1
6 = |6 - 5| = 1
6 = |6 - 5| = 1
6 = |6 - 5| = 1
✔️Find the sum of the distances of each data value from the mean
1 + 1 + 1 + 1 + 1 + 1 = 6
✔️Find the MAD:
MAD = 6/6
MAD = 1

Answer:
Sue travels for 3 hours and a half
Sue stays stationary for 2 hours and a half
Step-by-step explanation:
Everytime the curve climbs, it means Sue is travelling. Everytime the curve stays flat, it means Sue is stays stationary. It remains to count up the total for both categories, with one square being 30 minutes.
Sue spends 3.5 hours on travelling and 2.5 hours stationary.
What is distance-time graph?It is a graph which shows how far an object has travelled in a given time.
What is a stationary graph?It is graph of function which represents there is no change in the function value or the function value is constant.
What is change in value?"subtract old value from new value."
For given example,
Given distance-time graph represents a journey made by Sue.
Let 't' represents the travelling time and 's' represents the stationary time.
If we observe the graph,
from 2 pm to 3 pm Sue travelled 5 miles
⇒ t1 = 3 - 2
⇒ t1 = 1 hour
from 3.5 pm to 4 pm she travelled 10 miles
⇒ t2 = 4 - 3.5
⇒ t2 = 0.5 hour
from 5 pm to 6.5 pm she travelled 15 miles
⇒ t3 = 6.5 - 5
⇒ t3 = 1.5 hours
from 7.5 pm to 8 pm she travelled 5 miles
⇒ t4 = 8 - 7.5
⇒ t4 = 0.5 hour
So, the total travelling time would be,
⇒ t = t1 + t2 + t3 + t4
⇒ t = 1 + 0.5 + 1.5 + 0.5
⇒ t = 3.5 hours
Also, Sue spends stationary from 3 pm to 3.5 pm
⇒ s1 = 3.5 - 3
⇒ s1 = 0.5 hour
She spends stationary from 4 pm to 5 pm
⇒ s2 = 5 - 4
⇒ s2 = 1 hour
She spends stationary from 6.5 pm to 7.5 pm
⇒ s3 = 7.5 - 6.5
⇒ s3 = 1 hour
So, the total stationary time would be,
⇒ s = s1 + s2 + s3
⇒ s = 0.5 + 1 + 1
⇒ s = 2.5 hours
Therefore, Sue spends 3.5 hours on travelling and 2.5 hours stationary.

In a school, 10% of students have 7 ball pens, 30% of students have 3 ball pens, 40% of students have 2 ball pens and 20% of students have 1 ball pens. What is the expected number of ball pens of a student?
The expected number of ball pens of a student is 2.4.
What is the expected number?
In statistics and probability analysis, the expected value is calculated by multiplying each of the possible outcomes by the likelihood that each outcome will occur and then summing all of those values.
The expected number of ball pens of a student can be calculated by taking a weighted average of the number of ball pens that each group of students has.
The weight for each group is the percentage of students that are in that group.
So, we can calculate the expected number of ball pens of a student by:
(10% * 7) + (30% * 3) + (40% * 2) + (20% * 1)
0.7 + 0.9 + 0.8 + 0.2
The expected value is also known as the population means and it can be calculated by summing the product of each outcome’s probability and its corresponding value.
Here, the outcome is the number of ball pens.
Hence, the expected number of ball pens of a student is 2.4.

What are Parallel Lines Cut by Transversal?Straight, equally spaced lines that never cross each other and are on the same plane are called parallel lines. The angles that are created when any two parallel lines are intersected by a line (referred to as the transversal) have a relationship. Corresponding angles, Alternate Interior Angles, Alternate Exterior Angles, and Consecutive Interior Angles are some of the several pairs of angles that are created at this intersection.
Corresponding angles
When two parallel lines are intersected by a transversal, the corresponding angles have the same relative position
Alternate Interior Angles
Alternate interior angles are formed on the inside of two parallel lines which are intersected by a transversal.
Alternate Exterior Angles
The pairs of angles formed on either side of a transversal that divides two parallel lines are known as alternate exterior angles.
Consecutive Interior Angles
When two parallel lines are cut by a transversal, the pairs of angles formed on the inside of one side of the transversal are called consecutive interior angles or co-interior angles.
Given data ,
Let the angle be represented as ∠ABE
Now , let the line be EBC and the total angle of a straight line = 180°
And , the measure of ∠CBD = 40°
Since , ∠ABE and ∠CBD are vertically opposite angles ,
The measure of ∠ABE = measure of ∠CBD
Therefore , the value of ∠ABE = 40°
Hence , the measure of vertically opposite angle ∠ABE = 40°

Cos theta = -1/6 what is tan theta
Therefore , the solution to the given problem of trigonometry comes out to be tanθ = - √35 .
What is trigonometry?Trigonometry is the discipline of mathematics that studies correlations between angles and sides of triangles. Trigonometry is present in all of geometry because every straight-sided shape may be reduced to a set of triangles. Remarkably intricate connections exist between trigonometry and other areas of mathematics, particularly calculus, real or complicated, exponentials, logarithms, and infinite series.
Here.
Given : Cosθ = -1/6
To find : Tanθ
Since cosθ is in second quadrant
Thus,
Cosθ = B/H
According to pythagoras theorem,
H²= B²+ P²
=> 6² = 1² + P²
=> 36-1 =P²
=>P= √35
So ,
value of Tanθ comes out to be
=> tanθ = - √35 /1
=>tanθ = - √35
Therefore , the solution to the given problem of trigonometry comes out to be tanθ = - √35 .

Work out the perimeter of the rectangle.
The perimeter of rectangle could be 50.6 if a rectangle has an area of 7. 5 and One of the sides is 0. 3m in length.
What is Area of rectangle ?
area of rectangle could be the product of its sides that is length and breadth.
Given the area of rectangle is 7.5
one of its side, length = 0.3
let other side be x .
area = length*breadth
7.5 = 0.3 * x
x = 25
hence , other side could be 25.
perimeter of rectangle = 2 (length+breadth)
= 2 * (25+0.3)
= 2 * (25.3)
