Question

If f(x)=-3x+3, then f^-1 (x)=____
Please help

Answer 1

y = (-x/3) +1 or y = (-1/3 * x) + 1

Explanation:

For the inverse of a function, you invert the y and x positions.

In your case:

y = -3x+3

The inverted function is:

x = -3y+3

When you solve this for y, you get:

-3y = x-3

y = -x/3 +1
