Question

Which of the following functions best describes this graph. 50 POINTS!!

Answer 1

Answer:

D)  y = x² - 8x + 15

Step-by-step explanation:

x-intercepts are at x = 3 and x = 5

⇒ y = (x - 3)(x - 5)

⇒ y = x² - 8x + 15

Answer 2

Answer:

D is your correct answer

Step-by-step explanation:

This is a quadratic equation which means that it has two roots which is your X-Intercepts. As seen on the graph, your X-intercepts are 3 and 5 which are your roots. Simple bring them over to the other side so you have (X-3) and (X-5)

You now multiply them into each other:

(X-5)×(X-3)=0

: X^2-8x+15
