The vertex of a parabola that opens downward is at (0, 4). The vertex of a second parabola is at (0, –4). If the parabolas intersect at two points, which statement must be true?
The second parabola opens downward.
The second parabola opens upward.
The points of intersection are on the x-axis.
The points of intersection are of equal distance from the y-axis.

Respuesta :

Answer:

b

Step-by-step explanation:

The true statement is :

The points of intersection are of equal distance from the y-axis.

What is parabola?

A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point (known as the focus) and from a fixed straight line which is known as the directrix.

Given:

The vertex of a parabola that opens downward is at (0, 4).

The vertex of a second parabola is at (0, –4).

so, The points of intersection are of equal distance from the y-axis.

This is because the symmetry axis of both parabolas is x = 0, so the intersection points  should be at same distance from x- axis and y-axis.
