3 votes 3 votes $h’(x)$ is positive in interval $(-\infty, 0)$ and $(2, \infty)$ hence $h(x)$ is increasing function in these intervals.

Can you provide the video soution of such example? 3 votes 3 votes amitarp818 commented Dec 14, 2023 reply Follow Share @sarthakdarjiWe define the increasing and decreasing intervals using the first derivative of the function f(x) as:If f'(x) ≥ 0 on an interval I, then I is said to be an increasing interval.If f'(x) ≤ 0 on an interval I, then I is said to be a decreasing interval.The function is constant in an interval if f'(x) = 0 through that interval. 1 votes 1 votes Lucky1900 commented Jan 23 reply Follow Share how did you decide +, – on that number line 0 votes 0 votes Please log in or register to add a comment.
