Answer:

D. y =

Step-by-step explanation:

The solutions to this graph (meaning when y equals 0 or when the graph crosses the x-axis) are 4 and 5.

The only answer choice that has the solutions 4 and 5 when you factor it out is D.

Here's the proof:

x^{2} -9x  + 20

Factors of 20: - 5 & -4

Sums that add up to -9: -5 + (-4)

x^{2} -4x-5x+20

(factor the first two terms and the last two terms separately)

(x^{2}-4x)(-5x+20)

x(x-4) -5(x-4)

(x - 5) (x - 4)

Hope it helps (●'◡'●)
