Answer 10

You want to look for sign change in the graph. If the derivative goes from positive to negative at a point then it means there's a maximum for the function at that point point.

If the derivative graph goes from neg to pos at some point in the given interval then it implies that f has a minimum at that point.

In the graph u provided sign change occurs at 2b or 18. The graph of the derivative goes from neg to pos at 18 which implies that the function has a minimum at 18.

Answer 11

From the graph min point ( 1, -2)
