Which of the following functions best describes this graph? O A. y = (x+5)(x-4)
O B. y - (x - 3)(x-6)
O c. y = x2 +9x+18
O D. y = x2 - 2x + 4

c. y=x2+9x+18

Step-by-step explanation:

If we factor y=x2+9x+18 using the x method, the factors 3 and 6 mutliply to 18 as well as add to 9. that means y=x2+9x+18=(x+3)(x+6). From the graph, we can see that when y=0, it is at the x's -3 and -6. If we set (x+3)and(x+6) equal to zero (for ex. x+3=0), our x's are -3 and -6 which are the same zeros as the graph
