How would I go about adding points and a function to the same set of axes? For example I have a set of points already plotted, and I want to plot my function, f(x)=x^2 on the same graph to compare them.

Thanks.

Hi, does anybody know how I would create an array from a function.. for example:

Say I have the function y = x^2, and I am choosing the points 1-5 for x, how would I make an array to display all the values 1-5 and their corresponding y-values?

Help much appreciated.
