Question

Verify if f(x) = 1/2x - 2 and G(x) = 2x + 4 are inverses.

Answer 1

Yes, they are inverse functions

Explanation:

Hello!

Let's find the inverse of g(x) first.

Find the inverse

• g(x) = 2x + 4
• y = 2x + 4

Flip the x and y variables

• x = 2y + 4

Solve for y

• x - 4 = 2y
• 0.5x - 2 = y

The inverse of g(x) is the same as the function f(x).
