Plotting Overlapping Curves
Stupid newbie question!
I want to be able to plot two or more functions on a single graph. For example, I wish to plot $x^2$ and $2^x$, say in red and blue, such that a person can readily see, with their eyes, where the two curves intersect.
Unfortunately, I can't figure out how to make this happen. It seems like it would be a common teaching device but how to make it work?
Any assistance welcomed!
