Answer:
(d) (-2, 0) and (4, 0)
Explanation:
You want to identify the x-intercepts of the parabola shown in the graph.
X-intercepts
An x-intercept is a point where the graph intersects the x-axis. This graph crosses the x-axis at the points (-2, 0) and (4, 0). These are its x-intercepts.
Some graphs may only touch the x-axis, without crossing it. Such a touch point is also an x-intercept.
The x-intercepts of the parabola are (-2, 0) and (4, 0), choice D.

Additional comment
The y-value of any point on the x-axis is zero, so any x-intercept will have a y-coordinate of 0. That is, any point on the graph that has a y-coordinate of 0 is an x-intercept.
