The correct Answer is:
To solve the question, we need to analyze the implications of a graph intersecting the X-axis at two distinct points. ### Step-by-Step Solution: 1. **Understanding the Graph**: - The graph of a polynomial function intersects the X-axis at points where the function equals zero. These points represent the roots of the polynomial. 2. **Identifying the Nature of Roots**: - If the graph intersects the X-axis at two distinct points, it indicates that there are two solutions (or roots) to the equation represented by the graph. 3. **Types of Roots**: - Roots can be classified as: - Real: These are the roots that can be plotted on the number line. - Complex: These roots involve imaginary numbers and do not intersect the X-axis. - Rational: These are real roots that can be expressed as a fraction. - Irrational: These are real roots that cannot be expressed as a fraction. 4. **Analyzing the Given Condition**: - Since the graph intersects the X-axis at two distinct points, it implies that both roots are real numbers. This is because complex roots would not intersect the X-axis at all. 5. **Conclusion**: - Therefore, if the graph intersects the X-axis at two distinct points, the roots are necessarily real. ### Final Answer: The roots are necessarily **real**.
