The image shows a question asking about the interpretation of the mathematical limit \(\lim_{x \to a} f(x) = \infty\).

This expression means that as \(x\) approaches \(a\), the value of the function \(f(x)\) grows without bound, essentially tending to infinity. Let's review each of the options:

1. **"As \(x\) approaches \(a\), the value of \(f(x)\) increases without bound."**  
   - **Correct**: This directly describes the behavior indicated by the limit.

2. **"The value of \(x\) goes out to infinity, when it gets close to \(a\)."**  
   - **Incorrect**: The limit is about \(f(x)\), not \(x\). This statement suggests that \(x\) goes to infinity, which is not what the limit means.

3. **"The value of \(f(x)\) becomes infinite when \(x\) approaches \(a\)."**  
   - **Correct**: This restates the definition of the limit going to infinity.

4. **"This means that \(f(a) = \infty\)."**  
   - **Incorrect**: The limit as \(x\) approaches \(a\) does not necessarily mean \(f(a)\) itself is infinite. The function may not even be defined at \(a\).

5. **"The limit exists and equals infinity."**  
   - **Correct**: A limit can exist and be infinite. This is the correct interpretation of a limit approaching infinity.

### Summary:
The correct options are:
- Option 1: "As \(x\) approaches \(a\), the value of \(f(x)\) increases without bound."
- Option 3: "The value of \(f(x)\) becomes infinite when \(x\) approaches \(a\)."
- Option 5: "The limit exists and equals infinity."

Let me know if you want further details or explanations. 

Here are five related questions you could explore:
1. What is the difference between limits approaching a finite number and limits approaching infinity?
2. How does one handle limits where \( f(x) \) tends to infinity from one side but not the other?
3. What happens when \( \lim_{x \to a} f(x) = 0 \)?
4. Can limits exist for discontinuous functions at a point?
5. What is the relationship between limits and function continuity?

**Tip**: A limit approaching infinity means the function grows larger and larger, but this doesn't guarantee anything about the function's value at the specific point.

Which of the following is/are signified by lim x -> a f(x) = ∞?

Learn the interpretation of limits that approach infinity in calculus. Explore how functions behave as x approaches a value, and f(x) increases without bound. This problem explains key concepts such as the behavior near vertical asymptotes and limits at infinity, ideal for students in high school or introductory college calculus.
