Hello KA.  

The section on Exponential Growth & Decay in Algebra 1 needs some more help.  In the last part of the 1st section before the first quiz, Sal needs to make a video on writing the functions.  In the exercise, please decide on which form of answer you want (decimal or fraction), make a note of it to us students, and BE CONSISTENT!   You might even want to push that down to the next section which actually deals with writing functions!  

Also, the connecting graphs with contexts could use a video having Sal do an example. 

Thank you!
