Final answer:
The degree of the polynomial function g(x)=10x⁹-50x⁶-500x² is 9.
Step-by-step explanation:
The degree of a polynomial is the highest power of the variable (indeterminate) in the polynomial. In a polynomial expression, the variable is raised to various powers, and the term with the highest power determines the degree of the entire polynomial.
The polynomial function g(x)=10x⁹-50x⁶-500x² is a polynomial of degree 9. The degree of a polynomial is determined by the highest exponent on the variable, which in this case is 9. Therefore, the correct answer is option 1) 9.
