Which table identifies the one-sided and two-sided limits of function f at x=2?

ANSWER
The third table
EXPLANATION
From the graph the left hand limit is
[tex] lim_{x \to{2}^{ - } }(f(x)) = 4[/tex]
The right hand limit is
[tex]lim_{x \to{2}^{ + } }(f(x)) = 2[/tex]
Since the left hand limit is not equal to the right hand limit, the limit as x approaches to 2 does not exist.
[tex]lim_{x \to{2}}(f(x)) = non \: existent[/tex]
Answer:
3rd one (C)
Step-by-step explanation:
approaching from left side: 4
approaching from right side: 1
approaching 2: nonexistent because it is a jump discontinuity
