The concept of quadratic function

We call a function of the form y = ax ^ 2 + BX + C (where a, B, C are constants, a ≠ 0) quadratic function, a is the coefficient of quadratic term, B is the coefficient of linear term, C is the constant term. Generally, a function of the form y = ax ^ 2 + BX + C (a ≠ 0) is called quadratic function
