If I only want to draw a function to, let's say... only x < 2, how do I do that?
On the TI 84+, I wrote the function and put a (x<2) at the end of the function (for example 2X → 2X(x<2)

Just to clarify, what you are actually doing when you use 2X(X<2) is implied multiplication of 2*X*(X<2), that is you are multiplying 2X times the boolean result of X<2 which is either 1 or 0. In your example, for values of X>2, the graph is simply Y=0 which you can't see on the 84+ because the graph is the same color as the x-axis. If you turn off the axes (2nd-Format) you can see the full graph.

You could do the same thing on the Prime by entering 2X*(X<2), but now you will see the X>2 portion since the graph and x-axis are different colors (just as you would on the TI-84+CE).

A much better way of doing this is to use
{2X if X<2
which you can access in the Math Templates.

How do I draw a function with many values for parameters?
Unfortunately, this feature is not implemented on the Prime (yet?).
