WebA quadratic can be negative for some or all of the x values in its domain. This will depend on the coefficients, but a quadratic with three negative coefficients is not necessarily always negative. Remember that a quadratic function has the form: f (x) = ax2 + bx + c. where a, b, and c are real numbers and a is nonzero.
