Can someone explain to me how to do this exercise?
given the function f(x) = 3x-2x^2, evaluate and simplify.
1. f(f(-1))
2. f(-1+a)-f(-1)

Hi
You should put into them.I mean
1-This is 2 part.First, you should put f(-1) then you should put what you found.
Solve is:f(-1)=3(-1)-2(-1)^2 so -3-2=-5 then put in other one:if f(-5):-15-50=-65
Is it correct?
