Question 1 of 10
kvasek [131]

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

y=a(x-h)^2+k             ...(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

y=a(x-h)^2+v

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

Therefore, the correct option is A.
