To what degree is the polynomial function? a). second b). third c). fourth d). fifth

You have not provided the polynomial function, therefore, I cannot provide an exact answer.
However, I can help you with the concept.

The degree of the polynomial is determined based on the highest exponent in the equation.

For example:
x² + 2x + 3
highest exponent > 2
degree of polynomial > second

x³ + 2x⁵ + 7x⁴
highest exponent > 5
degree of polynomial > fifth

x + 9x³
highest exponent > 3
degree of polynomial > third

Hope this helps :)
