Question

Please help ASAP. The graph of a quadratic function is shown. Which of the numbers below could be the discriminant of the corresponding quadratic equation? a) 10 b) -1 c) 0 d) none of the above

Answer 1

a

Explanation:

Since the graph intersects the x-axis at 2 points, it has 2 solutions which means that the discriminant is greater than 0. The only option that satisfies this is 10.

Answer 2

10 option a)

Explanation:

The discriminant has to be a number greater than zero, since we clearly see two solutions (crossings of the x axis) of the curve. So, the only option larger than zero among the possible answers is 10 (option a)
