$$ 
   f(x) = \left\{
     \begin{array}{lr}
       x^2 &  \text{if} x\leq 5\
       x-1 & \text{if }  x >5
     \end{array}
   \right.
$$

anonymous · Answer

the "text" part is an unnecessary frill

anonymous · Answer

$$f(x) = \left\{
     \begin{array}{lr}
       x^2 &  \text{if } x\leq 5\
       x-1 & \text{if }  x >5
     \end{array}
   \right.$$

$$f(x) = \left\{
    \begin{array}{lr}
       x^2 &  \text{if } x\leq 5\
       x-1 & \text{if }  x >5
     \end{array}
   \right.$$hm... I knew it had array in it somewhere but have never seen the lr thing before.
