Answer: See below
Step-by-step explanation:
1. At x=1, the limit does not exist. If you see an open circle on the graph like you do here, you know that the function is discontinuous. This graph actually shows a jump discontinuity at x=1.
2. You can determine if a limit exists by solely looking at the graph. Unfortunately in this case, f(1)=1 and [tex]\lim_{x \to \ 1^-} f(x)[/tex] are not equal to each other. Therefore, the limit does not exist.
