Which of the following are polynomial functions?
Check all that apply.

A. F(x) = -x + 5x + 7-1
B. AX) = 5.3x2 + 3x-2
C. F(x) = 4x4-10
D. F(x) = x2 + 15x-3
E. F(x)=2x*-18x2 +5 - 10/x^2

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

step-by-step explanation:

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
