HELPPPPP ME PLEASEE

Which of the following are polynomial functions?
Check all that apply
I A. F(x) = 4x^4-10
B. F(x) = -x^3+5c^2+7 √7x-1
C. F(x)=3/5x^4-18x^2+5-10/x^2
D. F(x) = 5.3x^2 + 3x-2
E. F(X) = x^2 + 15x - 3

Answer 1

Answer: A and D

Explanation:

Answer 2

A, D and E

Explanation:

By definition, a polynomial consists of variables raised to exponents which are not fractions or negative, with the terms linked by arithmetic operators such as addition, subtraction etc

From this definition, A is a polynomial, B is not as it contains a square root which is a fractional power

C is not, as there is a negative power of x

D and E are polynomials too
