Find all functions 
such that![\[f(xonkrbo)=xonkrbo\]](http://latex.artofproblemsolving.com/f/c/6/fc675824e77e68b11f58e78a79f1b6b82990fe3f.png)
for all real numbers 
and 
Let 
be the set of positive real numbers. Determine, with proof, if there exists at least one function 
such that![\[f(x^x)=f(x)^{f(x)}\]](http://latex.artofproblemsolving.com/f/3/6/f36a23cab5d3ed8b6e2fd4df576cf1a4ff59c51a.png)
for all real 
in 
Determine all functions 
such![\[f(x+y)=f(y)\]](http://latex.artofproblemsolving.com/c/1/1/c1117c05e7ecb5262a9e39c01ff6e8e1d644324c.png)

Find all functions 
such that![\[f\left(x+\dfrac{1}{x}\right)+f\left(y+\dfrac{1}{y}\right)+f\left(z+\dfrac{1}{z}\right)=1\]](http://latex.artofproblemsolving.com/a/6/1/a6163664953f7b976b02b87cab3274191aca527f.png)
