State whether the function is a polynomial function or not. If it is, give its degree. If it is not, tell why not.
-$$f ( x ) = \frac { 2 - x ^ { 2 } } { 5 }$$
A) No; x is a negative term
B) Yes; degree 2
C) Yes; degree 1
D) No; it is a ratio

Question

Quizplus · Accepted Answer

The function is a polynomial because it can be simplified to $-\frac{1}{5}x^2 + \frac{2}{5}$, which is a polynomial of degree 2.
