10 points. y = a(x-h)^2 + k

Answer:
Option A [tex]\textbf{a}=\frac{\textbf{y-k}}{(\textbf{x-h})^2}[/tex]
Step-by-step explanation:
Verification: The given equation is
[tex]y=a(x-h)^2+k[/tex]
[tex]y-k=a(x-h)^2[/tex]
[tex]\frac{y-k}{(x-h)^2}=a[/tex]
which may be written as
[tex]a=\frac{y-k}{(x-h)^2}[/tex]
