No. A polynomial can have as many degrees as you like.
A quadratic function can have up to two roots. Depending on the discriminant (the expression under the square root in the quadratic formula), it can have two distinct real roots, one repeated real root, or no real roots at all (in which case the roots are complex). Therefore, the total number of roots, considering both real and complex, is always two.
A quadratic function can have either two, one, or no real roots, depending on its discriminant (the expression (b^2 - 4ac) from the standard form (ax^2 + bx + c)). If the discriminant is positive, there are two distinct real roots; if it is zero, there is exactly one real root (a repeated root); and if it is negative, there are no real roots, only complex roots.

It can have 1, 2 or 3 unique roots.
According to the rational root theorem, which of the following are possible roots of the polynomial function below?F(x) = 8x3 - 3x2 + 5x+ 15
A third degree polynomial could have one or three real roots.
4, the same as the degree of the polynomial.
Sort of... but not entirely. Assuming the polynomial's coefficients are real, the polynomial either has as many real roots as its degree, or an even number less. Thus, a polynomial of degree 4 can have 4, 2, or 0 real roots; while a polynomial of degree 5 has either 5, 3, or 1 real roots. So, polynomial of odd degree (with real coefficients) will always have at least one real root. For a polynomial of even degree, this is not guaranteed. (In case you are interested about the reason for the rule stated above: this is related to the fact that any complex roots in such a polynomial occur in conjugate pairs; for example: if 5 + 2i is a root, then 5 - 2i is also a root.)
A third-degree equation has, at most, three roots. A fourth-degree polynomial has, at most, four roots. APEX 2021
Each distinct real root is an x-intercept. So the answer is 4.

5, Using complex numbers you will always get 5 roots.
None, it involves the square root of a negative number so the roots are imaginary.
