O B. x= aly- n)2 + V
O c. x = aly - 1)2 + h
O D. y= a(x - 1)2 + 1

Respuesta :

Given:

A parabola opens up or down and its vertex is at the point (h, v).

To find:

The equation of the parabola.

Solution:

A parabola opens up or down. It means it is a vertical parabola.

The vertex form of a vertical parabola is

[tex]y=a(x-h)^2+k[/tex]             ...(i)

Where, a is constant and (h,k) is vertex.

The vertex of given parabola is at point (h,v). Putting h=h and k=v in (i), we get

[tex]y=a(x-h)^2+v[/tex]

The required equation of the parabola is [tex]y=a(x-h)^2+v[/tex].

Therefore, the correct option is A.

Answer:

A.
