Question

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

Answer 1

Answer:

  f^-1(x) = 1 -(x/3)

Step-by-step explanation:

To find the inverse function, solve for y:

  x = f(y)

  x = -3y +3

  x/-3 = y -1 . . . . divide by -3

  1 -(x/3) = y . . . . add 1

The inverse function is ...

  f^-1(x) = 1 -(x/3)

or

  f^-1(x) = (3-x)/3
