I assume you want the leading coefficient because there is only 1.
The leading coefficient is always in front of the term with the greatest exponent.
Leading coefficient = -1.
The degree of this function is 9. It is a ninth degree polynomial function. Why 9? It is a 9th degree polynomial because 9 is the greatest power.
