Homework Help: Calculus

Posted by Cesar on Wednesday, February 23, 2011 at 8:35pm.

Sorry for posting another quesiton..;

f(x) = { -7x^2 + 7x for x<=0
{ 3x^2 + 7x for x>0

According to the definition of derivative, to compute f'(0), we need to compute the left-hand limit
lim x-> 0− = _____
and the right-hand limit
lim x->0+ ______
We conclude that f'(0)= _____
Write DNE if the derivative does not exist.

Ok... I know that the answer for f'(0) is 7... I thought that the answers for the previous 2 were 0 because I was left with -7x for the left one and 3x for the right one... what am I doing wrong?
