What is the inverse of the function?
f(x) = 3^x + 1

f^-1(x)= log3 (x) +1
f^-1(x)= log3(x)-1

f^-1(x)=log3(x+1)

f^-1(x)=log3(x-1)

Answers

Answer 1

Answer:

f^-1(x)=logs3(x+1)

Step-by-step explanation:

Answer 2

Let y=f(x)

[tex]\\ \rm\Rrightarrow y=3^x+1[/tex]

Interchange

[tex]\\ \rm\Rrightarrow x=3^y+1[/tex]

[tex]\\ \rm\Rrightarrow lnx=ln(3^y+1)[/tex]

[tex]\\ \rm\Rrightarrow x=\dfrac{ln(y-1)}{ln3}[/tex]

Again interchange

[tex]\\ \rm\Rrightarrow f^{-1}(x)=\dfrac{ln(x-1)}{ln3}[/tex]

A has a volume of 264 cm3
B has a volume of 891 cm3

A has a height of 8 cm

Work out the height of pot B.

Answers

Answer:

27 cm

Step-by-step explanation:

the radious of the pot:

[tex]v=\pi r^{2} h[/tex]

[tex]264=\pi r^{2} (8)[/tex]

[tex]r^{2} =\frac{264}{8\pi }[/tex]

The height of pot B

[tex]891=\pi (\frac{264}{8\pi })h[/tex]

[tex]891=(\frac{264}{8} )h[/tex]

[tex]h=\frac{(891)(8)}{264} =27[/tex]

Helpp the topic is about limits

Answers

Since we want to find the value of k where the limit exists, set both equations equal to each other. Then substitute x = -1 in for each equation to find k.

[tex]kx - 3 = {x}^{2} + k[/tex]

1. Set both equations equal.

[tex] - k - 3 = 1 + k[/tex]

2. Substitute x = -1.

[tex] - 3 = 1 + 2k[/tex]

3. Solve for k by adding k to both sides. Continue the process of solving the equation.

[tex] - 4 = 2k[/tex]

[tex]k = - 2[/tex]

Thus, k = -2. Check by graphing the function.
