Yes What is the end behavior of the graph of the polynomial function y=10x9-4x

down-up

Step-by-step explanation:

Since 10x^9 - 4x is an odd function, we know its end behavior is either down-up or up-down.

(Picture a quadratic, which has a degree of 2. It's even, and its end behavior is up-up if it's positive or down-down if it's negative.)

10x^9 is positive, not negative, so we know its end behavior is down-up, not up-down.

(Picture x^3, which is a positive cubic. It's odd, and its end behavior is down-up. It would be up-down if it was -x^3.)

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!
