1. The problem statement, all variables and given/known data
Hello, I'm having some trouble with the following problem:

Solve y = x+$$\frac{1}{x}$$ for 0 < x $$\leq$$ 1

2. Relevant equations

y = x+$$\frac{1}{x}$$ for 0 < x $$\leq$$ 1

3. The attempt at a solution

I am not sure on how to start. I've spent a lot of time thinking about how to this problem, but have had no luck. The only thing comes to mind is that y = $$\frac{x}{x}$$ + $$\frac{1}{x}$$ = 1. This solution seems to trivial; I would greatly appreciate any help.

Thank you.

I'll assume the question instead means find the range of the function for the domain 0<x<1.

Are you allowed to use calculus?

I would start by finding the limit of y as x approaches 0+ and find y when x=1. If you can't use calculus then it will probably suffice to just explain that as x increases in that interval, y is always decreasing. This is enough information to give the range.
