Question 1137101
<br>
The range of any polynomial of odd degree is all real numbers, because the end behavior for large positive and large negative values is in opposite directions.<br>
For polynomials of even degree, the end behavior is in the same direction for both large positive and large negative values; that means the range of a polynomial of even degree will always have either a lower bound (if the leading coefficient is positive) or an upper bound (if the leading coefficient is negative).
