1. The problem statement, all variables and given/known data Where are the following functions discontinuous? f(x) = (x+2)/√((x+2)x) 2. Relevant equations 3. The attempt at a solution f(x) = (x+2)/√((x+2)x) = (x+2)/x√(2x) multiply both denominator and numerator by √(2x) = (x√2+2√x)/(x(2x)) Can I leave it like this and state that x ≠ 0, or have I gone horribly wrong? Otherwise, I'm a little lost. The other questions similar to this that I have done usually consist of factoring out and cancelling a binomial in the numerator with a binomial in the denominator.
