HELP ASAP.NO LINKS & NO TROLLING PLS use the zero and the labeled point to write the quadratic function represented by the graph.

A. y=x^2-2x-8

B. y=2x^2-12x+16

C. y=x^2+2x-8

D. y=2x^2+4x-16

A. x² - 2x - 8

Step-by-step explanation:

At x = -2, 4 graph cut x- axis. So, they are zeroes of f(x).

So, f(x) = k(x+2)(x-4), where k is a constant.

Now, (3, -5) in f(x), we get

-5 = k (3+2)( 3 -4)

-5 = -5k

k= 1

So, f(x) =  (x+2)(x-4)

= x² - 2x - 8

So, option A is right.
