Which is the graph of a quadratic equation that has a positive discriminant? On a coordinate plane, a parabola opens up. It goes through (negative 1, 4), has a vertex at (1, 0), and goes through (3, 4). On a coordinate plane, a parabola opens up. It goes through (negative 3, 4), has a vertex at (negative 1, 0), and goes through (1, 4). On a coordinate plane, a parabola opens up. It goes through (negative 2, 5), has a vertex at (0, 1), and goes through (2, 5). On a coordinate plane, a parabola opens up. It goes through (negative 2, 3), has a vertex at (0, negative 1), and goes through (2, 3).

The graph of a quadratic equation that has a positive discriminant is On a coordinate plane, a parabola opens up. It goes through (negative 2, 3), has a vertex at (0, negative 1), and goes through (2, 3).

What is the graph function about?

In any kind of graph function as in the above case, when the discriminant is said to be negative, the graph is one that cannot pass through the x-axis, and as such one cannot have x-intercepts on it.

Also known that when the discriminant is negative, that implies that the roots of the quadratic function are said to be not of real numbers and then the graph will not have x-intercepts.

Therefore, The graph of a quadratic equation that has a positive discriminant is On a coordinate plane, a parabola opens up. It goes through (negative 2, 3), has a vertex at (0, negative 1), and goes through (2, 3).
