Answer» Verify Rolle's theorem for each of the following functions on the indicated intervals

(i) f(x) = x2 − 8x + 12 on [2, 6]



(ii) f(x) = x2 − 4x + 3 on [1, 3]



(iii) f(x) = (x − 1) (x − 2)2 on [1, 2]



(iv) f(x) = x(x − 1)2 on [0, 1]



(v) f(x) = (x2 − 1) (x − 2) on [−1, 2]



(vi) f(x) = x(x − 4)2 on the interval [0, 4]



(vii)
f(x) = x(x −2)2 on the interval [0, 2]



(viii)
f(x) = x2 + 5x + 6 on the interval [−3, −2]
