Give a coordinates of the Vertex y =(x + 2)
.

squared - 1​

Given:

The equation of a parabola is:

To find:

The coordinates of the vertex of the given equation.

Solution:

The vertex form of a quadratic function is:

              ...(i)

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

We have,

                ...(ii)

On comparing (i) and (ii), we get

We know that the vertex of the parabola is (h,k).

Therefore, the vertex of the given equation is (-2,-1).

point a is the center of this circle.

the ratio of the lengths of (ef/bc) and (ad/ih) is 2: 1.
