Which table identifies the one-sided and two-sided limits of function at x = 2?​
Yuliya22 [10]

Answer:

Table 3

Step-by-step explanation:

Check table three;

lim\:_{x\to \:2^-}\:f\left(x\right)=\:4

lim\:_{x\to \:2^+}\:f\left(x\right)=\:1

Since the left hand limit (lim\:_{x\to \:2^-}\:f\left(x\right)) is not equal to the right hand limit (lim\:_{x\to \:2^+}\:f\left(x\right)),  the limit as x approaches to 2 does not exist.

Therefore "nonexistent" is true, and table 3 is the correct model of the limits of the function at x = 2
