How do you define the domain of a certain function? For example, how would you type in the following function (which also happens to a piecewise-defined function):

**f(x) = 2x+3, if −4 < x < 3; 2x+4, if x > 3**

I do know how to graph a function from x1 to x2 (the syntax is

*f(x),[x1,x2]*), but it's important to get the "grater/smaller than" sings right.

If it matters, I have fx-9750GII.
