Question

How do you find where a function is Increasing?

Answer 1

Finding Where the function is increasing :

To find where the function is increasing, it is important to determine the interval in which the function has a positive first derivative.

A function is increasing in an interval if its first derivative is positive in that interval.

Hence, calculate $f\text{'}\left(a\right)$, If $f\text{'}\left(a\right)>0$ then the function is increasing.
