    discriminantIn the Quadratic Formula, \(x=\frac{-b±\sqrt{b^2-4ac}}{2a}\), the quantity \(b^2-4ac\) is called the discriminant.    
    quadratic functionA quadratic function, where \(a\), \(b\), and \(c\) are real numbers and \(a≠0\), is a function of the form \(f(x)=ax^2+bx+c\).    
    quadratic inequalityA quadratic inequality is an inequality that contains a quadratic expression.
