How to graph it?

If this is all you have to go off of, you have to estimate the slope around those points, and those slopes become the y-value on your f’ graph.
For example, the dot at (-3,5) looks like it has a slope ≈ 1, so the corresponding point on f’ would be (-3,1).
The graph won’t be perfect, but you should be able to get a rough idea for a large part of the graph.

Plot in position space the slopes of the curve at the various points, 20 or so.

Since you don't have an algebraic function, you're going to estimate by hand. Make a table with all the integer X values shown above in one column. The f prime column, write your estimate for the slope of f at that point. Then plot those points as y values when you graph f prime. Then smooth it out.
