Answer:
Choice D is correct.
Step-by-step explanation:
Given expression is :
y=a(x-h)²+k
we have to simplify it.
y=a(x-h)²+k
Adding -k to both sides of above equation,we get
y-k=a(x-h)²+k-k
y-k=a(x-h)²+0
y-k=a(x-h)²
Dividing by (x-h)² to both sides of above equation,we get
y-k/(x-h)²=a(x-h)²/(x-h)²
y-k/(x-h)²=a(1)
y-k/(x-h)²=a
a=y-k/(x-h)² which is the answer.
