The correct statement regarding the relationship between the degree of a polynomial and the number of relative extrema it can have is:

The number of relative extrema of a polynomial is, at most, one less than the degree.

This means that if a polynomial has a degree \( n \), it can have up to \( n - 1 \) relative extrema. It is important to note that the actual number of relative extrema can be fewer than this maximum, depending on the specific polynomial.

Yes, I can confirm that the correct statement is:

The number of relative extrema of a polynomial is, at most, one less than the degree.

To elaborate:

  • A polynomial of degree \( n \) can have a maximum of \( n - 1 \) relative extrema. This is derived from the fact that the extrema are found by setting the derivative of the polynomial (which is of degree \( n - 1 \)) to zero. The roots of the first derivative can yield up to \( n - 1 \) critical points, which can correspond to relative maxima or minima.

Thus, while it is possible for some polynomials to have fewer than \( n - 1 \) extrema, they cannot have more than that. Therefore, the statement that the number of relative extrema is "at most one less than the degree" is accurate.
