The zeros of a quadratic function are the solutions of the related quadratic equation. If the graph of a quadratic function crosses the x-axis, there will be two real number solutions. If the graph of a quadratic function just touches the x-axis, there will be one unique real number, or double root, solution. If the graph of a quadratic function does not cross the x-axis, there will be no real number solution.
The equation for a quadratic is as follows: y = ax^2+bx+c
The first variable “a” determines whether the parabola opens up or down The squared allows the equation to look like the parabola swoop when graphed. The c term is the constant term
