Notice and learn it :   in this problem,  THERE  IS  NO  any quadratic equation.

There is a quadratic function,  instead.



The problem's questions do relate to the given quadratic function.

The problem's questions  DO  NOT  RELATE  to  QUADRATIC  EQUATION,   which does not present in this problem.
