1. The problem statement, all variables and given/known data f(0,1) ---> R by f(x) =1/x^(1/2) -((x+1)/x)^(1/2). Can one define f(0) to make f continuous at 0? 2. Relevant equations lx-x0l<delta lf(x)-f(x0l<epsilon 3. The attempt at a solution My thought is that the limit must equal f(0), but I'm unsure of how to get f(0) because of division by zero.
