Answer 2

Answer:

the right answer is false

Step-by-step explanation:

We can have cubic polynomials having less than 3 zeroes.

For example, The polynomial y = x3 + x2 + x + 1 has a degree of 3 but has only one real root, that is, x = -1.

The polynomial y = x3 + 11x2 + 6x + 1 also has only one zero, that is, x = -0.096.

A cubic polynomial can have a minimum of one zero, as a cubic curve always cuts the x-axis at least once.

Check out more about polynomial functions of degree 3 using the cubic function formula.

Hence, it is false that every polynomial function of degree 3 with real coefficients has exactly three real zeros.
