Let a function g : [0, 4] → R be defined as
then the number of points in the interval (0,4)where g(x) is NOT differentiable, is
Text Solution
Verified by ExpertsThe correct answer is:
3
(3)
f(x) = x 3 − 6x 2 + 9x − 3
f’(x) = 3x 2 − 12x + 9 = 3(x − 1)(x − 3)
f(1) = 1f(3) = −3
g(x) is continuous
g(x) is non-differentiable at x=3
