So I just recently got a TI-89 Titanium for free.
No, I didn't steal it.
A friend who didn't want it gave it to me, because he's odd.

Anyways, is there a program or application that will find the domain and range of a function for me?
Also, is there one that will find horizontal and vertical asymptotes?
Because I don't understand them.
But once I do understand, I want a shortcut, because I'm lazy like that.
Please, any help is greatly appreciated.

Domain is just the farthest the x intercepts will go.
Range is the farthest the Y intercepts will go.

On a parabola, it'd look like: {x|x E r} --> the E is actually a Greek letter Epsilon, I think. It means that X is any real number.

Y would look like {y|x E r, y > __} and you'd fill in the Y coordinate of the vertex. It will change based off your graph, but I'm assuming you're only doing quadratics or else you would probably already have to know what they are.

Circles and elipses are pretty simple. You just fill in the farthest points of your graph on each side.

EDIT: I don't know about those programs, but I want your calculator. 89 is, what, 250 dollars? 84 Platinums are 150.

I'm so jealous

Yeah my professor for calculus showed us how to put the programs in. I could go to the closet, and dig through mounds of boxes and fiddle around with the calculator for a while and write down the program for you but.... well I just don't feel like it.

I thought that the range was the x-intercepts, and the domain was the y-intercepts.
Maybe I just have a horrible math teacher.
If I had more programming knowledge I'd write my own program, but I think that would take forever.
