How do I solve for this Question

Letf(x)={13,x<−4,−x+9,−4≤x<4,2,x=4,6,x>4.

Sketch the graph of this function and find following limits if they exist (if not, enter DNE).


Letf(x)=.

{13, x<−4,

−x+9, −4≤x<4,

2 x=4,

6, x>4.

Sketch the graph of this function and find the following limits if they exist (if not, enter DNE).


1. limx→4−f(x)

2. limx→4+f(x)

3. limx→4f(x)

4. limx→−4−f(x)

5. limx→−4+f(x)

6. limx→−4f(x)

Did you sketch and label the function?

Grace L. Here is a Desmos graph to give you a clue on how to solve this problem. The table of values should give you an indication as to the various limits: desmos.com/calculator/rfviqhreqn
