From the graph, it looks like the polynomial is a one with a leading term that has an odd power, so this rolls out option 1 and 3.

This leaves us with option 4, 22x^9 as the right answer.
It can be used in statics for the major of Mechanical Engineering. You can find the total amount of weight on beams by forces.
12 would be your answer
-2*-1= 2
2*6=12
so 12
They are equal.
2/6 = 1/3
1 * 2 = 2
-------
3 * 2 = 6
do you see it?
