6-9.

Write the equation of the inverse, , for each of the following functions.

Solve for

:

Then 'switch' the input and the output.*f*^{ −1}(*x*) = log_{2}*x*

This is the reverse of part (a).

Recall that e is a constant. (It's value is between

and )

Be sure to divide both sides by

before you solve for .
