the limits of integration for dx are -1 and 1

so i know this graph is an ellipse.. but i don't know how to graph it, seeing that it's not an equation (like x^2+y^2=1). so i can't visualize exactly what it is, so i don't know how to visualize the polar graph. agh i'm completely confused. any hints at how to attack this beast?
