Question

f(x)=x(x^2-x-2) Determine whether Rolle's Theorem can be applied to f on the closed interval [a,b]. If Rolle's Theorem can be applied, find all values of c in the open interval (a,b) such that f'(c)=0.

Answer 1

I've found the derivative: 3x^2-2x-2

Answer 2

WRONG INSTRUCTIONS! SORRY! Determine whether the Mean Value Theorem can be applied to f on the closed interval [a,b]. If the Mean Value Theorem can be applied, find all values of c in the open interval (a,b) such that f'(c)=f(b)-f(a)/b-a

Answer 3

Are we using the same function for these instructions? :)

Answer 4

yes!
