The correct Answer is:
To solve the problem, we need to determine which graph represents a function \( p(x) \) that has four distinct zeros. A zero of a function is a value of \( x \) for which \( p(x) = 0 \), and graphically, these zeros correspond to the points where the graph intersects the x-axis. ### Step-by-Step Solution: 1. **Understand the Concept of Zeros**: - Zeros of a function are the x-values where the function equals zero. In a graph, these are the points where the graph crosses the x-axis. 2. **Identify the Requirement**: - We need to find a graph that intersects the x-axis at four distinct points. This means the graph must have four separate x-intercepts. 3. **Analyze the Options**: - We will evaluate each option to see how many times it intersects the x-axis. 4. **Evaluate Option A**: - Check how many times the graph intersects the x-axis. - **Result**: It intersects the x-axis only two times. - **Conclusion**: This option does not have four distinct zeros. 5. **Evaluate Option B**: - Check how many times the graph intersects the x-axis. - **Result**: It intersects the x-axis three times. - **Conclusion**: This option does not have four distinct zeros. 6. **Evaluate Option C**: - Check how many times the graph intersects the x-axis. - **Result**: It intersects the x-axis two times. - **Conclusion**: This option does not have four distinct zeros. 7. **Evaluate Option D**: - Check how many times the graph intersects the x-axis. - **Result**: It intersects the x-axis four times. - **Conclusion**: This option has four distinct zeros. 8. **Final Decision**: - Since only Option D intersects the x-axis four times, it is the correct representation of the function \( p(x) \) with four distinct zeros. ### Conclusion: The correct answer is **Option D**.
