What is a function rule?The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given data ,
Let the function be represented as f ( x )
Now , the value of f ( x ) is
f ( x ) = x - 4 be equation (1)
On simplifying , we get
The inverse of the function is given by replacing x with y
So , the value of the function is
y = x - 4
x = y + 4
On interchanging , we get
f ( x )⁻¹ = x + 4
Hence , the inverse is f ( x )⁻¹ = x + 4

What is triangle?A triangle can be referred to as a polygon with three edges and three vertices.
we can arrange length of one side of a unique triangle in 3 different ways.
Let x,y,z be the length of the three sides.
For triangles to be unique, length of one side can be arranged in 3 different ways.
Then, length of 6.5 cm can be at maximum three positions which is x,y,z.
The 2.5 cm lenght can appear to be at maximum three positions which is x,y,z.This can as well be done for 6cm.

The average attendance at school for 5 days was 264. If the attendance on the 5th day was 256, calculate the average attendance for the first 4 day’s
Answer:
266
Step-by-step explanation:
Let the attendence of 5days be a,b,c,d,e
given,
(a+b+c+d+e)/5=264
a+b+c+d+256=264*5 [since 5th day=256]
(a+b+c+d+)/4=1(320-256)/4 [dividing both side by 4]
average attendence of 4 days =266
Problem 2 Six different jobs need to be done today at the restaurant where you work. You have a pool of nine available workers. If you can assign only one worker to each job and no more than one job to a worker, how many different worker/job assignments are possible
========================================================
Explanation:
The order matters because the jobs are different. This means we'll use a permutation.
We have n = 9 workers to pick from and r = 6 jobs to fill.
Plug those values into the nPr permutation formula.
[tex]n P r = \frac{n!}{ (n-r)! }\\\\9 P 6 = \frac{9!}{ (9-6)! }\\\\9 P 6 = \frac{9!}{ 3! }\\\\9 P 6 = \frac{9*8*7*6*5*4*3*2*1}{ 3*2*1 }\\\\9 P 6 = 9*8*7*6*5*4 \ \ \text{.... Note: The 3*2*1 cancels}\\\\9 P 6 = 60480\\\\[/tex]
There are 60480 ways to assign the 9 workers to the 6 different jobs where order matters.
----------------------
Another approach:
Label the 6 jobs as A,B,C,D,E,F
For job A, we have 9 workers to pick from.
For job B, we have 8 workers to pick from. This is because it states that there is "no more than one job to a worker".
For job C, we have 7 workers to pick from. And so on. We have this countdown going on. We stop once we reach job F.
We end up with 9*8*7*6*5*4 = 60480 different permutations
The string "9*8*7*6*5*4" is found in the second to last step of the section above.

Find the DIAMETER of a circle for the circumference given.
circumference = 81 km
A) 4 km B) 10 km
C) 12 km D) 8 km
Answer:
25.796... km
Step-by-step explanation:
We are given that:
Circumference: 81 kmFormula of circumference:
2πr or πdThus, we can rewrite the circumference as:
2πr = πd = 81 kmSince we are asked to determine the diameter, it is recommended to use the formula (πd). Therefore,
πd = 81 kmDivide π both sides to isolate the diameter:
⇒ πd/π = 81 km/π ⇒ d = 81 km/πSubstitute π as 3.14 and simplify:
⇒ d = 81 km/3.14 ⇒ d = 25.796... kmTherefore, the diameter of the circle is 25.796... km.
