Step-by-step explanation:

For no. 3

x - 3 = 3 - x

x + x = 3 + 3

2x = 6

x = 6 / 2

x = 3

For no. 4

3(x + 4) = 3x + 4

3x + 12 = 3x + 4

3x - 3x = 4 - 12

0 = - 8

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
