Solution

Breakdown the Problem

  1. Identify the equation that intersects with the x-axis. The points of intersection occur when y=0 y = 0 .
  2. Find the roots (values of x x ) where the equation equals zero.

Relevant Concepts

  1. For a quadratic equation in standard form ax2+bx+c=0 ax^2 + bx + c = 0 , the points of intersection with the x-axis can be found using the quadratic formula: x=b±b24ac2a x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}
  2. The discriminant D=b24ac D = b^2 - 4ac determines the nature of the roots. If D>0 D > 0 , there are two distinct real roots.

Analysis and Detail

  1. Without the explicit equation provided, we cannot calculate exact values. However, typically, we substitute the values of x x given in the options to see if y=0 y = 0 holds true.
  2. Evaluate the provided options:
    • a. x=2 x = -2 and x=4 x = 4
    • b. x=2 x = 2 and x=4 x = -4
    • c. x=2 x = 2 and x=4 x = 4
    • d. x=2 x = -2 and x=4 x = -4

Verify and Summarize

  1. To confirm the intersections, the roots must satisfy the equation y=0 y = 0 for each of the x x values given in the options.
  2. Check each option against the standard forms of quadratic equations that can intersect the x-axis at those points.

Final Answer

As the specific equation is not provided, I cannot determine the exact option that describes the points of intersection. Please provide the specific equation or check with the given values to see which pairs correctly satisfy the condition y=0 y = 0 . Typically, two distinct real roots will yield two intersections, and based on the common structure, options might often represent standard roots for typical quadratic equations.
