How do i find the end behavior of a function?

1. If the degree n of a polynomial is even, then the arms of the graph are either both up or both down.

2. If the degree n is odd, then one arm of the graph is up and one is down.

3. If the leading coefficient an is positive, the right arm of the graph is up.

4. If the leading coefficient an is negative, the right arm of the graph is down.

Step-by-step explanation:

-3(b-8)-5=9(b+2)+1

distribute

-3b+24-5=9b+18+1

add/ subtract

-3b+20=9b+19

20-19= 1

-3b+1=9b

9b+3b= 12b

1=12b

1 divided by 12 = 1/12

answer: 1/12 = b
