Find the derivative by the limit process? Can someone check my work? For the answer I get 3x^2-12 but my text book says it's 3x^2+12

Are you positive the original function is: f(x) = x^3 - 12x ??

OpenStudy (anonymous):

Yes I just checked right now when you said that. It gives me exactly that function.

OpenStudy (dumbcow):
