I need to create a table where the rows are one variable and the columns are another variable, but within the table is the values of the function created by the 2 other variables. Also, from that I need to create specifically a 2D graph where the x and y are the variables and the plot itself is the function. This seems simple, but I'm just stuck. Any input will help please!

I'm not sure about the "table" you want. Here's a simple example of how to define two vector values, then compute a 2D result and plot it.
x = [1:10];
y = [21:30];
[X,Y] = meshgrid(x,y);
Z = sqrt(X.^2 + Y.^2);
surf(X, Y, Z)

Ah, so this is homework.
Surely, you can figure out how to generate your output array from the help you've been given so far. You just have to change the sqrt expression in something even simpler.

I'm not sure what you mean? do you have any references on creating tables such as those?
