Question

Which of the following describes this graph

Answer 1

D) y = x² - 8x + 15

Explanation:

The graph has two roots at x = 3, and x = 5. This means that (x - 3) and (x - 5) are factors of the equation of the line

So far, the equation is y = (x - 3)(x - 5), since there is no coefficient of x²

Next if we expand, we get y = x² - 8x + 15, which is D

Hope this helps!
