To start class, we took an exponential growth and decay quiz. This took up a majority of the class, so we only had about 20 minutes left to take notes.

Our notes were about the basic information of exponential functions. 

This equation was given to us…
f(x)=b^x
b= base and is positive and not 1

There were also graphs shown, but the photos are unavailable at this time.

The second part of our notes consisted of information about graph transformations. I will list the most important review and rules we learned…

y=a*b^k(x-d) +c

a= vertical stretch/compression
c= vertical shift up or down
k= horizontal stretch/compression
d= horizontal shift left or right
*if there is a negative sign in front of the a then it reflects over the x-axis
*if there is a negative sign in front of the k then it reflects over the y-axis
