Hey! So I've been learning about the Key Features of Linear and Exponential Funtions in class for the past couple of days (I'm in Algebra 2) and I really don't understand it... And we have a quiz tomorrow. Our textbook is no help at all, and I couldn't find anything on the internet. So can someone please explain to me the key features? (Domain, Range, Average Rate of Change, Positive and Negative) I know it's a lot of trouble, but it'd be awesome if someone could explain it to me.

Thanks!
