How do you solve this and which answer choice is right and why?

a) c= -3/2

b) c= 0,3

c) Rolle's Theorem does not apply as f is not continuous on [0,2]

d) Rolle's Theorem does not apply as f(0) does not equal f(2)

e) none of these

Tutors, please sign in to answer this question.

Lana,

This is straight forward based upon the definition of Rolle's Theorm:

*"If a real-valued function ƒ is continuous on a closed interval [a, b], differentiable on the open interval (a, b), and ƒ(a) = ƒ(b), then there exists a c in the open interval (a, b) such that f'(c) =0."*

The closed interval for f is [0,2]. f(0)= 0 and f(2)= 10. f(a)≠ f(b). f(x) does not meet the conditions of Rolle's Theorem. Answer=d.
