Question

If a quadratic function has two solutions, what would you expect to see on the graph of its parabola? The parabola crosses the x-axis twice. The parabola touches the x-axis once. The parabola does not touch or cross the x-axis. The parabola has an infinite number of solutions.

Answer 1

The graph of a curve crosses the x-axis n times, where n is the amount of solutions (roots) it has.

So if it's a quadratic function (with 2 solutions) we can say that it the graph will cross the x-axis twice
