Question

state the degree and leading coefficient of the polynomial in one variable. if it is not a polynomial in one variable, enter none for both degree and leading coefficient. 18 - 3y + 5y² - y⁵ + 7y⁶ degree = 6, leading coefficient = 18

Explanation:

Step1: Identify highest power of $y$

The polynomial is $18 - 3y + 5y^2 - y^5 + 7y^6$. The highest exponent of $y$ is 6.

Step2: Find leading coefficient

The term with the highest power is $7y^6$, so its coefficient is 7.

Answer:

degree = 6, leading coefficient = 7
