Write the equation of the inverse, , for each of the following functions. Homework Help ✎

  1. Solve for x: log2y = x
    Then 'switch' the input and the output.

    f −1(x) = log2x

  1. This is the reverse of part (a).

  1. Recall that e is a constant. (It's value is between 2 and 3)

    f −1(x) = ex

  1. Be sure to divide both sides by 5 before you solve for x .
