On slide 96, when you are doing the function. You have (-6)2=36. or the f(8)=36. If the 2 outside the parenthesis is an exponent then this is correct. As it is written though, it is -6 x 2, which would equal -12 or f(8)= -12. I wanted to clarify which way this equation is supposed to go. I was losing my mind thinking I forgot some step in functions because I thought the equation was the latter, not the former.
