In short, to find a limit graphically, you simply follow the graph horizontally, until you reach the desired x-value, at which point you then look to see the what the corresponding y-value is, or is approaching. To be more specific, suppose you are looking for the limit as x approaches from 5 from the RIGHT side of #y=x^2#.
In order for a function to have a limit at x =a, in your case a =0, then the limit when x approaches a from the right must equal the limit when x approaches a from the left. In this case, the limit from the left is -1 and the limit from the right is 1. So, the only candidates to limit of f at 0 are -1 and 1.
