Not certain if this would help, but you can look at the code by left-clicking on this. I was not absolutely sure how to find the brace with which to show a list of equations; I could only find simple left or right brace in the tex tool of the forum.

To see some code, try clicking on this:
$f(x)=\begin{cases} 2x+c&x < -5\\ 3x^2&-5 \leq x < 0\\ cx^2&0 \leq x\\\end{cases}$

The tags may need to be 'tex' instead of 'latex' .

$$f(x)=\begin{cases} 2x+c&x < -5\\ 3x^2&-5 \leq x < 0\\ cx^2&0 \leq x\\\end{cases}$$

Could you instead open the LaTex reference guide? To open it, do this:
Left-Click on one of those lists of the equations I posted. A small window showing code will be displayed. Look in the bottom of that window for the LaTeX Code Reference link. This will display the LaTeX Reference Guide. Still, I'm not aware of how to give the larger right-hand brace; only the left-hand brace according to both the Code Refernce Link and the LaTex Reference Guide. Either of those will show you code to accomplish basically what you want.

Tell us if you have trouble opening those windows; but you should at least have no difficulty in opening both of those windows. First the Latex Code Source window (by clicking on the text image of the listed equations) and then on the LaTeX Code Reference Guide (which is a pdf file).

Let me try something; I'm not usually good at this, but this attempt comes directly from the Code Reference pdf file:

f(x)=\left\{\begin{array}{cc}0,&\mbox{ if }
x\leq 0\\1, & \mbox{ if } x>0\end{array}\right

That was without the tags.

With the [ t e x ] tags, it is:
$$f(x)=\left\{\begin{array}{cc}0,&\mbox{ if } x\leq 0\\1, & \mbox{ if } x>0\end{array}\right$$
