Use the given graph to determine the limit, if it exists. find lim f(x) x\to 3a. -1b. 7c. -3d. does not exist

Correct choice is D

Step-by-step explanation:

The graph of the function shows that the function is not continuous at point x=3.

When moving to the point x=3 from the left side, you can see that y approaches to -1. When moving to the point x=3 from the right side, then y approaches to -3 and at x=3, y=7. This gives you that the limit doesn't exist.

so, converting firstly the mixed fractions to improper fractions and then "adding".
