If the following is a polynomial function, then state its degree and leading coefficient. If it is not, then state this fact.
-$$f ( x ) = - 9 x ^ { 3 } - 4 - 19 x ^ { 4 } + x ^ { 9 } + 14 x ^ { 2 }$$
A) Degree: 9; leading coefficient: 1
B) Degree: 9; leading coefficient: $- 9$
C) Not a polynomial function.
D) Degree: 3 ; leading coefficient: $- 9$

Question

Quizplus · Accepted Answer

The given function is a polynomial of degree 9, with the highest power of x being 9. The leading coefficient, which is the coefficient of the term with the highest power, is 1.

If the Following Is a Polynomial Function, Then State Its f(x)=−9x3−4−19x4+x9+14x2f ( x ) = - 9 x ^ { 3 } - 4 - 19 x ^ { 4 } + x ^ { 9 } + 14 x ^ { 2 }f(x)=−9x3−4−19x4+x9+14x2

If the Following Is a Polynomial Function, Then State Its $f ( x ) = - 9 x ^ { 3 } - 4 - 19 x ^ { 4 } + x ^ { 9 } + 14 x ^ { 2 }$
