6. Determine whether Rolle's Theorem can be applied to the function f(x)=x -8x+/ on the closed interval [4,8]. If Rolle's Theorem can be applied, find all values of c in the open interval (4,8) such that J (C) = 0 A) Rolle's Theorem applies; c = -6 B) Rolle's Theorem applies; c = 5 C) Rolle's Theorem does not apply D) Rolle's Theorem applies; c = 6 E) Rolle's Theorem applies; c = 7
