I would like to plot two functions and shade in the area between them to illustrate an integration example.

I have this into mathematica:

Plot[{4 - x^2, 8 - 2 x^2}, {x, -2, 2}]

with this result:

enter image description here

I tried using the drawing tools to no avail. Is there a simple way to shade in the contained region between the two plots?

Thanks in advance!
