   1. The problem statement, all variables and given/known data
   
   Prove that if f is continuous at a, then so is |f|
   
   2. Relevant equations
   
   
   
   3. The attempt at a solution
   I know
   lim f = L
   x->a
   
   Not sure really where to go from here.

   to prove that f is continuous at a, you must prove that [tex]f(a)[/tex] is defined, that [tex]\lim_{x \to a} f(x)[/tex] exists and that [tex]\lim_{x \to a} f(x) = f(a)[/tex].
