I'm going to assume you meant x2 if -2 < x < 2
In order for a limit to exist, f(a) must exist, limf(a) x-->a must exists, and limf(a) x-->a must equal f(a)
By looking at the graph, the limit of -2 does not exist because there's a jump discontinuity and the left and right limits are not equal
a = -2
