State whether the function is a polynomial function or not. If it is, give its degree. If it is not, tell why not.
-$f ( x ) = - 14 x ^ { 3 } + 9 x ^ { 2 } - 7$
A) Yes; degree 6
B) Yes; degree 5
C) Yes; degree 3
D) No; the last term has no variable

Question

Quizplus · Accepted Answer

The function is a polynomial because it is a sum of monomials, each with a non-negative integer exponent. The highest degree of any term is 3, making the degree of the polynomial 3.
