Evaluate Logarithms and Graph Logarithmic Functions

Practice:Simplify the expression:

1. Find the inverse of 2. Find the inverse of

Evaluate Logarithms and Graph Logarithmic Functions

Graphing:We have seen that the inverse of an exponential function is a logarithmic function and vice versa.

That means that their graphs should reflect… no pun intended… that.

Let’s pay attention to the domain and range of both graphs.
