Answer :

EXPLANATION:

The given equation is a quadratic function, therefore it is of the form f (x) = ax² + bx + c, a ≠ 0; where the letters a, b and c are the coefficients; and always the coefficient c of a quadratic function is called constant.

The coefficients a, b and c of the quadratic function are as follows:
