Question

MATH HELP PLEASE!!!!!!!!

Answer 1

f(x)=7x-6
we rewrite it for easier calculations
y=7x-6
Now, we have to find x
7x=y+6
x=(y+6)/7
Now, we need to write instead of x --->y, and instead of y ---->x
y=(x+6)/7
So, correct answer is D

Answer 2

Hi there! The answer is D.

Function
f(x) = 7x - 6.

To find the inverse we need to switch the places from x and y.
y = 7x - 6

x = 7y - 6
-7y = -x - 6
7y = x + 6
y = (x + 6) / 7
