Question

Which parabola will have a minimum value vertex?

On a coordinate plane, a parabola opens down with x-intercepts at (negative 2.2, 0) and (2.2, 0), and a y-intercept at the vertex (0, 5).


On a coordinate plane, a parabola opens down with a vertex at (0, 0).


On a coordinate plane, a parabola opens down with x-intercepts at (negative 1, 0) and (2.3, 0), a y-intercept at (0, 2), and has a vertex at (0.75, 2.5).


On a coordinate plane, a parabola opens up with x-intercepts at (negative 2, 0) and (2, 0), and a y-intercept at the vertex (0, negative 4).

Answer 1

Answer:D

Explanation:

Answer 2

On a coordinate plane, a parabola opens up with x-intercepts at (negative 2, 0) and (2, 0), and a y-intercept at the vertex (0, negative 4).

Explanation:

Parabollas are characterized by being curves which opens upside or downside.

When the parabolla opens upside, then we say it has a minium.

When the parabolla opens downside, then we say it has a maximum.

In either the minium or maximum point is defined by the vertex.

As you can observe, among the choices, the last one is the only one that opens up, therefore, it has a minimum value vertex.
