By the Mean Value Theorem, we know there exists at least one c in the open interval (–2,2) such that f(c) is equal to this mean slope.

For this problem, there are two values of c that work. The smaller one is_____ and the larger one is ______?

f(2)=32-4=28

f'(c)=(28-(-28))/(2-(-2))=14

f'(c)=12c^2-2=14

c^2=16/12=4/3

c=+-2/sqrt(3)
