Can the graph of a linear function have an undefined slope? Provide an explanation.

SOLVED: Let F be the function whose graph is shown below.Evaluate each of the following expressions.(If a limit does not exist or is undefined, enter "DNE".)1. limx→−1−F(x)=2. limx→−1 F(x)=3. limx→−1F(x)=4. F(−1)=5. limx→1−F(x)=6. limx→1 F(x)=7. limx→1F(x)=8. limx→3F(x)=9. F(3)=The graph of y = F(x).
