Question
Use a graphing utility to generate the curve $y=x^{3} /\left(1+x^{2}\right)$ in the $x y$ -plane, and then use the graph to help sketch the surface $z=y^{3} /\left(1+y^{2}\right)$ in 3 -space.
Step 1
Using a graphing utility (such as Desmos, GeoGebra, or a graphing calculator), we can plot the curve y = x^3 / (1 + x^2). The graph will show that the curve has a horizontal asymptote at y = 0 and increases as x approaches positive or negative infinity. Show more…
