State whether the function is a polynomial function or not. If it is, give its degree. If it is not, tell why not.
-$f ( x ) = \frac { 2 - x ^ { 4 } } { 9 }$
A) Yes; degree 1
B) No; x is a negative term
C) No; it is a ratio
D) Yes; degree 4

Question

Quizplus · Accepted Answer

The function is a polynomial because it can be simplified to a form where all the exponents of x are whole numbers, and the highest degree of x is 4.
