To determine the correct description of the point of discontinuity from the graph, let's analyze the provided image.

Observations from the Graph:

1. The graph has a break (discontinuity) at $x = 1$. At this point, the graph has a hole, and then it continues from a different value. This indicates a jump discontinuity.
2. There is no apparent discontinuity at $x = -3$. The graph seems continuous at this point.

Conclusion:

The correct answer is:

• c. there is a jump discontinuity at $x = 1$

Would you like more details or have any further questions?

Here are some related questions to consider:

1. What is the difference between a jump discontinuity and a removable discontinuity?
2. How can you algebraically identify the location of a discontinuity in a function?
3. What types of functions typically exhibit jump discontinuities?
4. How does a removable discontinuity differ from an asymptote?
5. How can discontinuities affect the derivative of a function?

Tip: When dealing with graphs, carefully examine the behavior of the function at specific points to identify different types of discontinuities.
