Quadratic equations are of the form \[ax^2 + bx + c\] Use the discriminant: \[b^2-4ac\] If the discriminant is positive, the specific quadratic has two intercepts. If the discriminant is negative, the specific quadratic is imaginary (no intercepts). If the discriminant is equal to 0, there is one intercept.
