What version of Mathematica are you using? If you are using version 5.1
or later, then you may avail yourself of the new built-in function
Piecewise. For example, you may type in an input cell:
Piecewise[{{-2, x < 1}, {x, 1 <= x < 3}, {5 - x^2, x â?¥ 3}}]
The corresponding output cell will display with a properly-sized curly
brace on the left.
Then if you want such an expression to the right of, say "f(x) = " in a
text cell, Convert that output cell to TraditionalForm and copy it into
the in-line math portion of the text cell where you are typing.
I'm sorry, but now that Piecewise exists, I've quite forgotten how to do
this as in earlier versions. It was alway real pain, as I recall.
