Question 172594
in this problem i'm asked to graph the equation. And then find the domain and range. the equation is 4xsquared + 4ysquared-12=0 
i took this and divided everything by 4 
and got 
x^2 + y^2 =3 
--------------------
The graph is a circle with its center at (0,0) and a radius of sqrt(3)
Domain: [-sqrt(3),sqrt(3)]
Range: [-sqrt(3),sqrt(3)]
