Line 6: [[Image:Polynomialdeg2.svg\|thumb\|right\|A quadratic polynomial with two [[real number\|real]] roots (crossings of the {{mvar\|x}} axis).]] The [[graph of a function\|graph]] of a [[function of a real variable\|real]] single-variable quadratic function is a [[parabola]]~~, a [[curve]] that has an [[axis of symmetry]] parallel to the {{tmath\|y}}-axis~~. If a quadratic function is [[equation\|equated]] with zero, then the result is a [[quadratic equation]]. The solutions of a quadratic equation are the [[zero of a function\|zero]]s (or ''roots'') of the corresponding quadratic function, of which there can be two, one, or zero. The solutions are described by the [[quadratic formula]]. A quadratic polynomial or quadratic function can involve more than one variable. For example, a two-variable quadratic function of variables {{tmath\|x}} and {{tmath\|y}} has the form
