Write an equation for the circle

Given:

The graph of a circle.

To find:

The equation of the given circle.

Solution:

The standard form of a circle is

         ...(i)

Where, (h,k) is vertex and r is the radius.

From the given graph it is clear that the radius of the circle is 4 units and the center of the circle is (-2,2).

Putting and in (i), we get

Therefore, the equation of the circle is .

i can't see the picture : /

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.
