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. **Does this concept sound familiar, yet strange? Your teacher may call these points by their nicknames.

### Other Terms for *x*-intercepts

- zeros
- roots
- solutions
- solution set

### Four Methods of Finding the *x*-intercepts

This article focuses on using a graph to identify the x-intercepts. Before you begin this tutorial, make sure that you can confidently plot ordered pairs on a Cartesian Plane.
