Which of the following are polynomials? Check all that apply.

A, B, C, E Step-by-step explanation: A. F(x) = 3x-^3 - 19 is a Polynomial of degree 3 B. F(x) = 2x^2 + 5x - 3 Is a Polynomial of degree 2 or a quadratic function C. F(x) = -x^3 + 5x2 + 7x - 1 is also a polynomial of the degree 3 D. F(x) = -x^3 + sq -x is not a polynomial due to the square root operation E. F(x) = 3/5x^4 - 18x^3 + x^2 - 10x + 3.5 is a Polynomial of the degree 4 What is a Polynomial? In mathematics, a polynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non negative integer exponents of variables.

Step-by-step explanation:

homozygous. one is homozygous, while two is heterozygous.

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
