Answer:

Step-by-step explanation:

y=a(x-0)(x-2)

=a(x^2-2x)

=a(x^2-2x+1-1)

or y=a(x-1)^2-a

(1,5) lies on it.

5=a(1-1)^2-a

5=0-a

or a=-5

so y=-5(x-1)^2+5

$- \frac{6}{2}$

And than we simplify this fraction to 2 and find the answer -3. I would be glad if you choose my answer the best. Good lessons ♡
