The condition is .

Squaring on each side.

Compare it to .

Center = (0, 0) and absolute value . 

Center at (0, 0) and ,So we plot

Up : (0, 0 + 3) = (0, 3)

Down : (0, 0 ) = (0, )

Left : (0 , 0) = (, 0)

Right : (0 + 3, 0) = (3, 0)

Graph

1. draw the coordinate plane.

2. Plot the center at (0,0).

3. Plot 4 points " radius away from the center in the up, down, left and right direction.

4. Sketch the graph connecting through the points.

To graph of is :
