If

f(x)=4^{\sin x}

satisfies the Rolle's theorem on

[0, \pi]

, then the value of

c \in(0, \pi)

for which

f^{\prime}(c)=0

is

View answer and explanation

Correct option: C

c=\pi / 2

Option C (

c=\pi / 2

) is correct because it satisfies the condition

f'(c) = 0

within the interval

(0, \pi)

after applying Rolle's theorem.

f(0)=2, f(1)=6, g(0)=0, g(1)=

2 , then there exists

0 < \mathrm{c} < 1

such that
Assertion (A): If Rolle's theorem be applied in

f(x)

, then L.M.V. theorem is also applicable for

f(x)

.
Reason (R): Both Rolle's theorem & L.M.V. theorem can not be applied in
