Two vertices of a rectangle lie on the x-axis and the other two vertices lie on the curve y = e^(-x^2) . Find the maximum area of the rectangle.(adsbygoogle = window.adsbygoogle || []).push({});

I can't understand with the question and I can't imagine the real diagram as I don't know how to sketch y = e^(-x^2) graph.I hope that somebody will try to draw me out the diagram so that I can understand better and I can solve this question later.I know that my request is too "EXTREMITY" but somebody please help me.

Thanks for anybody that spend some time on this question.
