Graph "any" equation (electronically) for free.

Isn't living in the year 2009 so much easier than 1989?

I remember graduating from high school 20 years ago, when computers were still kind of a novelty, and were often more trouble than they were worth. Remember formatting disks? Remember word processing software where you had to type in special symbols to make things show up in italics? Remember writing programs on the computer that made the computer count from one to one hundred?

I know. . . . there is a good chance that if you are reading this message, then you were not even born in 1989. But the times sure have changed.

This website is rather rudimentary, but it is evidence that it is easier to do just about anything today than it used to be. And you do not have to pay $89+ for a graphing calculator. You can actually graph equations just by plugging the formula into a box on this website: http://www.freemathhelp.com/equation-grapher.html.

The claim that you can graph "any equation" is false. I unsuccessfully tried graphing y = log(x). [College Algebra]

But I was able to graph a quadratic equation two ways: (1) by using x*x for the "x squared" term; and (2) by using x^2 for the "x squared" term. [Math 0099, College Algebra].

I also was able to find the intersection of two graphs. [Math 0099]
