Hello, all! By accident I found a way to write piece-wise functions . . with a "brace" at the left end only. f(x) = \begin{Bmatrix} x+3 & x < 2 \\ 6-x & x \ge 2 \end{array}
Wow so many different ways. I have to throw in my two cents f(x) = \begin{cases} x+3, \quad x < 2 \\ 6-x. \quad x \ge 2 \end{cases}
