We know the the equation has the form of a circle, and that the center is in the coordinate (0,0) because c and w are not been modificated.
we also know that the radius of the circol will be:
[tex]r=\sqrt[]{4}=2[/tex]
no with this information we can grph the equation:
Now in the graph we can see that x can just take values between (-2, 2) and y can take values of (-2, 2) so:
Domain: [-2, 2]
Range: [-2,2]
