Pretty sure i got it, just wanted someone to check my work.

Find the numbercthat satisfies the conclusion of Rolle's Theorem.f(x) =x3 -x2 - 12x+ 8

[0, 4]

I find the derivative, and set to 0

3x^2-2c-12=0

use the quadratic formula and i get 2.3609 and another number that cant be it since its not in [0,4].

How'd I do?

Thanks.
