X^3-2x^2-5x+6
From the shape, you can immediately tell it’s one of the x^3 functions. Then I just put both in my calculator and looked for which one matched
I thin the answer is D.DF
160 is 100% of 160, 480 is 4 times that. So 400%
So it would be 3s + 7s + 11s + 15s + 19s + 23s + 27s. Hope this helps
