Which of the following statements is FALSE?

1.It is possible that for a parabola and a line to intersect exactly once

2.The y-intercept of the quadratic function is always higher than the y-coordinate of the vertex.

3.If a quadratic function has no x-intercept, then its discriminant must be less than 0.

4.Assuming a parabola has 2 x-intercepts, then the vertex would be exactly halfway between them.
