Question

What's the inverse of f(x) = x-3/5

Answer 1

y = x + 3/5

Explanation:

1. Label this function 'y': y = x - 3/5

2. Interchange x and y: x = y - 3/5

3. Solve this for y: y = x + 3/5

This last result is the inverse of the given function.

Answer 2

y = x + 3/5

Explanation:

change f(x) to 'y'

y = x - 3/5

interchange 'x' with 'y'

x = y - 3/5

solve for y

y = x + 3/5
