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.
$18 - 3y + 5y^2 - y^6 + 7y^4$
degree = \boxed{6}, leading coefficient = \boxed{18}

Explanation:

Step1: Rearrange polynomial by degree

$$7y^4 - y^3 + 5y^2 - 3y + 18$$

Step2: Identify highest degree

The highest exponent of $y$ is 4.

Step3: Identify leading coefficient

The coefficient of the term with degree 4 is 7.

Answer:

degree = 4, leading coefficient = 7
