What is an x-intercept of a Quadratic Function?

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
