Answer:
Step-by-step explanation:
When you follow the curve from the left toward x=2, you wind up at the open circle at (2, 4). The limit from that direction is 4.
When you follow the curve from the right toward x=2, you wind up at the open circle at (2, -4). The limit from that direction is -4.
[tex]\lim\limits_{x \to 2^-}{f(x)} =4\\\\\lim\limits_{x \to 2^+}{f(x)} =-4[/tex]
