f

is a real-valued function defined on

\mathbb{R}

such that

f^{\prime}(x)=e^x(x-1)(x-2)

then

f

decreases in the interval

View answer and explanation

Correct option: C

(1,2)

Option C ((1,2)) is correct because the function f decreases where its derivative f'(x) is negative, which occurs in the interval (1, 2).
