Hey there! :)

If you switch it around, it becomes: -9 + 1 = 4b

-9 + 1 = -8

<u>-8</u> = <u>4b</u>
 4     4

-8 ÷ 4 = -2
4b ÷ 4 = b

-2 = b

Hope this helps :)

What can you say about the end behavior of the function ?
Evgesh-ka [11]
If the degree is even, then both ends of the graph go in the same direction, either both up or both down

if the degree is odd then both ends go in oposite directions

if the leading coefient (coefient of the highest powerd placeholder) is negative, then 2 possiblities could happen

1. if the degree of te function is even, then both ends point up
2. if the degree is odd, then the ends go from top left to bottom right


so we've got f(x)=-4x^6+6x^2-52
even degree and negative

so both ends point down
goes from bottom left to bottom right

B and D are the answers
