Can you write down f(x)? How does c come into it?

What's the exact wording of the problem? You titled this thread "Homework help limits" but as you have stated the problem, I don't see that limits enter into things. From the graph, f(x) appears to be defined for all x such that -5 <= x <= 5.

If the question is asking about continuity, of which you give no indication, then you need to look at limits a the three points of discontinuity.
