Best ResponseYou've already chosen the best response.0Are you sure you typed the function correctly? At the moment you have the solution right there, if you're supposed to find the domain you'd typically have a function like this: f(x) = 1/x + 2x Without actually having a answer like you have: f(x) = 3/x = 6, since that just gives x = 1/2.

Best ResponseYou've already chosen the best response.0To find the domain you want to know what value x can have while the function still is valid. So the only thing you got to worry about is 3/x. When does 3/x not evaluate to a correct value?

Best ResponseYou've already chosen the best response.0It's not as hard as it seems, the solution is that the function is valid for all values of x except for x = 0, that would evaluate to 3/0 which is invalid. That's basically how you're supposed to see it, what can x be without making the function break the rules of math. :)
