Hello, can anyone please help me by telling me how to graph more than one
function on the same graph; and also how I would go about graphing "non
functions", ex. graphing y= +/-Sqrt[x].
Also, is there any way to be able to just *show* the function that I input?
ex. (x(x + 2))/x^2 that would come out as:
x(x + 2)
---------
x^2
instead of the simplified form:
2 + x
-------
x
Lastly, how would I go about doing regressions? I tried reading the help
files but it did not help me much. For example, if I want to find the
formula for the quadratic equation with the points (1, 3), (-1, -3), (2, 6)
what command would I put in?
Any help would be greatly appreciated, thanks in advance.
