Determine whether Rolle's theorm can be applied on the closed interval [a, b]. If Rolle's theorm can be applied, find all vales of c in the interval [a,b] such that f'(c)=0. If Rolle's theorm cannot be applied, explain why not.

Best ResponseYou've already chosen the best response.1\[f(x)=x^36 x^2+11 x6\] \[f'(x)=3x^212x+11\] so rolle says there somewhere in [1,3] there is a number c with \[f'(c)=0\] set \[3x^212x+11=0\] solve for x
