Program or website for graphing

[Ginepri]

I'm in grade 11 pre-calc right now and my teacher gave us an assignment over the long weekend where we need to draw a person using the different kinds of graphs we learned (ie. hyperbolas, parabolas, circles, ellipses, lines etc.) I have a sketch of what I want on a piece of paper and I've written down all the equations of each line.

My Question Is: Is there a program or website that will allow me to enter all the equations and then plot all the lines together so I can see if it looks like what it's supposed to look like?

Maybe try
https://www.desmos.com/calculator
(I don't know how complicated your equations are)

Thanks! I'll give it a try. Is there ways to add inequalities. For example if I am drawing a line but I want it to stop at a certain point, I can say like x < 15

WolframAlpha is interesting, too.
Limits: "plot x^2, x from 2 to 4"

There is a "hack" if you cannot directly draw inequalities: sqrt(x-a)/sqrt(x-a) is not well-defined (for most plotting programs) for x<=a and 1 for x>a. It is possible to include an upper limit in a similar way.

Yes you can. You can look at the help area of the site: is the screenshot (attached) the type of thing you were interested in?
