No.
A quadratic function is a second degree polynomial, that is, is involves something raised to the power of 2, also know as squaring. Quadratus is Latin for square. Hence Quadratic.

Yes, but in this case, the coefficients of the polynomial can not all be real.
A polynomial of degree 2.
No.

True
by synthetic division and quadratic equation
They are both polynomial functions. A quadratic is of order 2 while a cubic is of order 3. A cubic MUST have a real root, a quadratic need not.

Try the quadratic formula. X = -b ± (sqrt(b^2-4ac)/2a)
A parabola is a graph of a 2nd degree polynomial function. Two graph a parabola, you must factor the polynomial equation and solve for the roots and the vertex. If factoring doesn't work, use the quadratic equation.
No. It would not be a polynomial function then.
