question
what is the degree of the polynomial $f(x)$ defined below?
$f(x) = -x^2 - 2x + 9 - x^4 - x^3$

Explanation:

Step1: Rearrange polynomial by degree

$f(x) = -x^4 - x^3 - x^2 - 2x + 9$

Step2: Identify highest exponent

The term with the highest power of $x$ is $-x^4$, where the exponent is 4.

Answer:

4
