To find the domain of a function, you typically look for any values of \( x \) that would result in undefined operations, such as division by zero or taking the square root of a negative number. However, since you mentioned using graphing technology, here's how you'd typically approach it:
1. **Graph the function** using appropriate graphing software or a calculator.
2. **Observe the x-axis** for any restrictions or points where the function is undefined.
Given the options you provided, either the domain is affected by some restrictions in the function's expression (not visible here) or by its behavior at certain points on the graph.
If we assume the function might have a restriction at \( x = -3 \) or \( x = 4 \), the domains represented could potentially hinge on their behavior near those points:
- **All real numbers**: This option is available if there are no restrictions at all.
- **(-3, ∞)**: This option suggests the function is defined for \( x > -3 \).
- **(4, ∞)**: This suggests the function starts becoming valid only from \( x > 4 \).
- **[4, ∞)**: This implies the function is defined starting at \( x = 4 \) and includes that point.
To determine the correct domain, check the graph for the specific function involved.
If you have the function and can provide it, I can help analyze it more specifically. Based on your quiz setup, if you observed a point where the function becomes undefined at \( x = -3 \) or a starting point at \( x = 4 \), you can select accordingly from the options stated.
