f(x)=\sin x, x \in[-\pi / 2, \pi / 2],

then which one of the following is not correct?

View answer and explanation

Correct option: C

fof(x)

is decreasing on

[-\pi / 2,0]

and is increasing on

[0, \pi / 2]

The correct answer is C because

fof(x)

is increasing on the entire interval

[-\pi / 2, \pi / 2]

, not decreasing on

[-\pi / 2,0]

and increasing on

[0, \pi / 2]
