The domain of a function is the set of values of the independent variable for which the function is defined. (your independent variable is 
in all cases presented here).
All of the functions you are dealing with here are either polynomial functions or rational functions. The domain of any polynomial function with real coefficients is the entire set of real numbers. The domain of any of the rational functions represented here is the set of all real numbers excluding any value that would cause a denominator to be zero.
