I'm given a graph with x approaching and hitting 1, making y=2 (filled dot). Then there's a discontinuity jump at (1,3) which is the empty dot, then there's 2 other points on this small curve with empty dots at (3,4.5) and at (5,4), then another jump to a filled dot at (5,1).

For the first question being find point c that the function has jump discontinuity but is left-continuous which I know would be c=5.

It's the second question that doesn't make sense to me. It is:

What value should you assign to g(c) to make f right - continuous at x=c?

This question just doesn't make sense to me. What is g(c) on the graph? The empty dotted curve? Would by "f" he meant the whole f(x) function which has discontinuity?

Thanks!!
