Which of the following functions is in vertex form?

Answer:
Y = a(x-h)^2 +k
Step-by-step explanation:
The first one, since the vertex form is in subtraction form. You need the a, the x, the h, and the k for the formula.
Answer:
y=a(x-h)^2+k
Step-by-step explanation:
This is the answer because numbers in the -h and k is the vertex point in this form.
e.g. y=2(x-4)^2+5
the vertex here is (4,5)
(btw, for h, when there's a negative sign in front of it, it's the opposite and when there's a plus sign in front of h, it's the opposite.)
