Topic: function

I just started and just a basic task I could not do....how do I graph, say y=x or y=xsquared, I went to new function, right of the function box is f(x)=   ...so I put y in box, got error message, no such variable etc, I tried f(y) and x=y and y =xsquared etc with same result, my help doesn't work, something about microsoft

Re: function

In Insert function you only enter the function itself, i.e. x for f(x)=x or x^2 for f(x)=x^2.  Insert relation on the other hand is more flexible and allows you to enter an equation like y^2=x.
