Answer:

f⁻¹(x) = -1/3x +4

Explanation:

You want the inverse function when f(x) = -3x +12.

Inverse

The inverse function can be found by solving for y the equation ...

x = f(y)

x = -3y +12

3y = -x +12 . . . . . . . add 3y -x

y = (-x +12)/3 = -1/3x +4

The inverse function is ...

f⁻¹(x) = -1/3x +4
