Answer 1

Answer:

A.

Step-by-step explanation:

So we are given the function:

$f(x)=7x+8$

To find the inverse of the function, we simply need to flip f(x) and x and then solve for f(x). Thus:

$x=7f^{-1}(x)+8\\x-8=7f^{-1}(x)\\f^{-1}(x)=\frac{x-8}{7}$

So the answer is A.

Answer 2

Answer:

$\large \boxed{\mathrm{Option \ A}}$

Step-by-step explanation:

f(x) = 7x+8

Write f(x) as y.

y = 7x + 8

Switch variables.

x = 7y + 8

Solve for y to find the inverse.

x - 8 = 7y

$\frac{x-8}{7}$ = y
