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

The fourth one. A parabola that opens up has a minimum at its vertex — here the parabola with vertex (0, −4) (x-intercepts at (−2,0) and (2,0)).
