Tue May 15 
Equations and Graphs of Exponential Functions To apply transformations to exponential functions, and discover
how to determine the equation of an exponential function given its graph. Click here
for an algorithm for finding equations of exponential functions given their
graphs. We will use our knowledge of inverses to graph inverses of
exponential functions.
