(3) Plot the level curves for values of c from 0 to 3, increasing in increments of 0.5. (give desmos some time for this)

(4) Imagine drawing a level curve of value c for EVERY 0<c<3. What would we get?
13
(5) Imagine raising a level urve of value c into 3D up to the plane z=c.
14
To see what we get, rotate the "xy-plane" into the "xyz-space.
