Answer:
A
Step-by-step explanation:
If there are 8 turning points in a polynomial graph, then the degree of the polynomial is n+1 or 9. On the other hand, this also applies to the number of zeros present in the function. If there are 7 zeros, then the degree is 8. Adding both degrees results to the resulting polynomial's degree is 16.
I’m pretty sure that I’m pretty sure that question 2 is 1 minute and 40 seconds. And for number 3 I got B. 0.25 because if you look at where the line makes a direct cross between pounds and dollars that first one is 8 pounds for 2 dollars. If you divide 8 by 2 you will get 0.25. Hope this helped :)
6x^2 + x - 15 = 6x^2 - 9x + 10x - 15 = 3x(2x - 3) + 5(2x - 3) = (3x + 5)(2x - 3)
Therefore, the other factor is 3x + 5.
