Question

1. what is the leading coefficient of the polynomial (9x^{5}-4x^{3}+3)?

a. 3
b. -4
c. 9
d. 4

Explanation:

Step1: Identify highest degree term

The polynomial is $9x^5 - 4x^3 + 3$. The term with the highest exponent of $x$ is $9x^5$.

Step2: Extract coefficient of this term

The coefficient of $x^5$ in $9x^5$ is 9, which is the leading coefficient.

Answer:

c. 9
