1-37.
  1. Find the inverse of each function below. Use correct notation to express your answer. Homework Help ✎

    1. f(x) = 3x3 − 5

    2. g(x) = square root of 2x plus 4

    3. h(x) = x2 − 2

Substitute y for the function notation.

Switch every x to y and every y to x.

Solve for y.

Add 5 to both sides:

Divide both sides by 3.

Take the cube root of both sides:

y = 3x3 − 5

x = 3y3 − 5
