Question 142452
graph, identify the conic section, and find the domain and range of 2x^2+y^2=36
------------------
{{{graph(400,300,-10,10,-10,10,sqrt(36-2x^2),-sqrt(36-2x^2))}}}
-----------------
Ellipse
----------------
Rewrite as:
x^2/18 + y^2/36 = 1
Domain: -sqrt(18) <= x <=sqrt(18)
Range: -6 <= y <= 6
