Its graph is a straight line. A quadratic function has an equation of the form \(y = ax^{2} + bx + c\) where \(b\) and/or \(c\) can be equal to zero, but \(a\) is not equal to zero. Its graph is a ...

A quadratic graph is produced when you have an equation of the form \(y = ax^2 + bx + c\), where \(b\) and \(c\) can be zero but \(a\) cannot be zero. All quadratic graphs have a line of symmetry.
