Circle shifted two units left and one unit up

Work Step by Step

This conic is a circle. Notice from the graph that the center of the circle is shifted 2 left and 1 up. This can be verified from the equation. $(x+2)^2+(y-1)^2=4$ The $(x+2)$ means that the center is shifted two units left (across the x-axis). The $(y-1)$ means that the center is shifted up one unit (up the y-axis).
