Question

What is the inverse of f(x) = 2x − 8?

Answer 1

B

Explanation:

To find inverse you switch f(x) and x use y for f(x) then solve for y.

1. x = 2y - 8

2. x + 8 = 2y

3. (x + 8) / 2 = y

4. 1/2x + 4 = y

Answer 2

Explanation:

firstly firstly we have to suppose f(X) as y and then solve it by interchanging X and y.
