### Infinite Geometric Series

Students explore infinite geometric series. They will consider the effect of the value for the common ratio and determine whether an infinite geometric series converges or diverges.

### Inverses of Functions

Students explore three ways to find the inverse of a function. First, students graph two scatter plots and find the line of reflection. Then, they will graph a line and use the x- and y-intercepts to create the graph of the inverse.
