Question

List two more functions that are inverses of each other.

Answer 1

Hello, Turley.

You can choose any function and then find inverse of it to answer this question.

Let's say we have y = 3x +4. We need to find inverse of this linear function.

We have 2 easy steps to find inverse of the function:

1. Switch x and y,
2. Solve for y.

First step: x = 3y +4

Second step: x = 3y +4 (cancel 4)

x -4 = 3y (cancel 3)

(x-4)/3 = y

so, we have two functions which are inverse of each other

y = 3x +4 and y = (x-4)/3

Hope that helps.
