Which graph shows a quadratic function with a discriminant value of 0?

On a coordinate plane, a parabola opens up. It goes through (negative 2, 0), has a vertex at (0.5, negative 6.2), and goes through (3, 0).

On a coordinate plane, a parabola opens down. It goes through (negative 2, 0), has a vertex at (0, 4), and goes through (2, 0).

On a coordinate plane, a parabola opens up. It goes through (negative 2, 4), has a vertex at (0, 0.5), and goes through (2, 4).
