I solved that the integral for this is Integral -1 to 1 (y^2 -3 -e^y) dy
antiderivative of that is y^3/3 -3y -e^y from -1 to 1
plug in those intervals, you get
(1^3/3-3(1)-e^1) - (-1^3 -3(-1)-e^-1)
What would be the final answer of that? I'm terrible with calculating the end result, but I understand the problem as a whole though. Thanks!
