# Thread: f ' and corresponding points on f graph

1. ## f ' and corresponding points on f graph

If I am given the f ' graph, with zeros A and C and minimum B maximum D.
Which points will correspond to a maximum/minimum/point of inflection on the f graph?

I am having difficulty thinking of the points when going from the f ' graph to f graph and vice versa.

2. The zeros on $f'$ will be turning points on $f$ . From here are $A,B,C$ and $D$ in order going along the x-axis?

3. I know they're turning points, but how do I know which ones?
And yes, A B C D are in order along the x-axis, but only A and C are on the x-axis. B is a minimum on f ' and D is a maximum on f ' .
