Question

A positive B negativeC zero D the parabola opens upE the parabola opens downF the parabola has 2x intercept’s

Answer 1

Recall the form of a quadratic equation:

`ax^2+bx+c=0`

When the value of a is negative, the parabola opens down and when the value of a is positive, the parabola opens up.

In the given graph, the parabola opens up. Then, the value of a must be positive.

Therefore, the a value of the function represented in the graph is positive because the parabola opens up.
