Question

(calc !) based on the graph of the derivative f`(x), identify the x value that is local maximum point for the function f(x)

Answer 1

Solution: C. X=-2

Analysis:

When we graph the derivative of a function, we can find a local maximum or minimum point, where the graph takes a maximum or minimum value, it's a maximum point for the initial function.

In this case, the point would be X=-2. At that point, the graph has a minimum value.
