These are 3 questions and 3 answers.

1) Find


[tex] \lim_{x \to \ 2^+} f(x)[/tex]

Answer: 4.

Explanation:

The expression means the limit as the function f(x) approaches 2 from the right.

Then, you have to use the function (the line) that comes from the right of 2 and gets as close as you want to x = 2.

That is the line that has the open circle around y = 4, and that is the limit searched.

2) Use the graph to determine the limit if it exists.

Answer:

[tex] \lim_{x \to \ 2^-} f(x) = 3[/tex]

[tex] \lim_{x \to \ 2^+} f(x)=-3 [/tex]

To determine each limit you use the function from the side the value of x is being approached.

Note, that since the two limits are different it is said that the limit of the function as it approaches 2 does not exist.

3) 
Answer: - 1


[tex] \lim_{x \to \ 3^-} f(x) = -1 [/tex]

To find the limit when the function is approached to 3 from the left you follow the line that ends with the open circle at (3, -1).

Therefore, the limit is - 1.
