Math Problem Statement

Use the graph to determine the values of x at which the function is not continuous.

Solution

From the graph you have provided, the function appears to have discontinuities at specific points where the graph is either interrupted, jumps, or contains holes.

Discontinuities:

  1. At x=5x = -5: There is a vertical asymptote, indicating a discontinuity where the function approaches infinity or negative infinity. The graph sharply dips downwards toward -\infty from the left of x=5x = -5 and continues from above after x=5x = -5, which suggests the function is not defined at x=5x = -5.

  2. At x=7x = 7: There is a small circle or "hole" in the graph, meaning the function is not defined at this exact point, despite the function continuing smoothly elsewhere.

Conclusion:

The function is not continuous at x=5x = -5 and x=7x = 7. These are the points where the function either has an asymptote or a hole.

Would you like further details or explanations about these discontinuities? Here are five related questions to deepen your understanding:

  1. What is the definition of a discontinuous function?
  2. How do asymptotes relate to discontinuities in a function?
  3. What types of discontinuities exist (e.g., removable, jump, and infinite discontinuities)?
  4. How can you determine if a function has a removable discontinuity?
  5. What role do limits play in identifying discontinuities in functions?

Tip: In cases where a function appears to have a hole, the discontinuity may be removable if the function can be redefined to fill that hole!
