What is the most zeros can a cubic function have?

A cubic polynomial can have three zeros because its highest power (or degree) is three. A quadratic polynomial may have no real solution but a cubic polynomial always has at least one real solution. If a cubic polynomial does have three zeros, two or even all three of them may be repeated.

Can a cubic function have more than 3 zeros?

The degree of the function indicates how many zeros the given function will have, therefore, the cubic function, since the degree is three, can have at most three zeros and it is not possible to have more than three.

What is the maximum of a cubic function?

A cubic function can also have two local extreme values (1 max and 1 min), as in the case of f(x) = x3 + x2 + x + 1, which has a local maximum at x = −1 and a local minimum at x = 1/3. These are the only options.

Can a cubic function have 4 real zeros?

The answer is no. Just as a quadratic polynomial does not always have real zeroes, a cubic polynomial may also not have all its zeroes as real. But there is a crucial difference. A cubic polynomial will always have at least one real zero.

Can a polynomial have infinitely many zeros?

Any nonconstant polynomial p(x,y)∈C[x,y] will always have infinitely many zeros. If the polynomial is only a function of x, we may pick any value for y and find a solution (since C is algebraically closed).

Can a cubic equation have more than 3 roots?

Therefore the numbers of roots of a cubic equation are three and these roots can be real roots or the complex roots. We know that any real root can also be written in the complex form i.e. with the imaginary part \[a + \left( 0 \right)i\]. Therefore, we can say that a cubic equation can have three complex roots.
