Here are the above questions using Latex:
Great, you have a calculator.
MathMan, I thinkmeansy = (lnx)(squared)
You need x-intercept, y-intercept, extrema (you might not get all three because some functions do not have some), and a few points. You must know the domain (x-range) so you know what to plot. Ask, or determine yourself.
1. Find those by hand or by a calculator... just plug x into the function. A calculator produces a much better estimate for the points.
2. Plot them.
3. Connect the dots as smoothly as possible.
