Find the center and radius of the circle (x + 1)^2 + y^2 = 4

This is the form of a circle. Use this form to determine the center and radius of the circle.

Match the values in this circle to those of the standard form. The variable

r

represents the radius of the circle,

h

represents the x-offset from the origin, and

k

represents the y-offset from origin.

The center of the circle is found at

These values represent the important values for graphing and analyzing a circle.
