Question

The graph of y = f’(×), the derivative of f(x), is shown below. List the intervals where the graph of f is increasing.

Answer 1

Given

The graph of derivative of the function is given.

Required

The intervals where the function is increasing.

Explanation

To determine the function is increasing, the derivative of the function should be greater than zero.

From the given graph it is clear that the derivative of the function is greater than zero for the interval

$(0,4)$Answer

Hence the function is increasing in the interval (0,4).

The correct option is D.
