1. The problem statement, all variables and given/known data Find all values x=a where the function is discontinuous. For each value of x, give the limit of the function as x approaches a. f(x)=[x^2-4]/[x-2] 2. Relevant equations 3. The attempt at a solution ok the first thing I did was factored out: (x+2)(x-2)/(x-2), then I crossed out the x-2 and ended up with f(x)=x+2...then I checked the answer and the answer was 2,4 I don't understand how they got 2,4 besides that f(x) can't equal 2, because then it'd be undefined.
