Question

why we use derivatives for increasing decreasing function ??

Answer 1

Answer:

$\large{\red{\underline{\tt{Answer}}}}$

The derivative of a function may be used to determine whether the function is increasing or decreasing on any intervals in its domain. ... If f′(x) > 0, then f is increasing on the interval, and if f′(x) < 0, then f is decreasing on the interval.

Answer 2

We use derivatives for increasing and decreasing functions because it determines the function of increasing or decreasing in any intervals of domain.
