The graph of a quadratic function is a parabola. A parabola can cross the x-axis once, twice, or never. These points of intersection are called x-intercepts or zeros. In your textbook, a quadratic function is full of x 's and y 's. This article focuses on the practical applications of quadratic functions. In the real world, the x 's and y 's are replaced with real measures of time, distance, and money. To avoid confusion, this article focuses on zeros and not x-intercepts.
