The range of a function is the set of all the mutiple possible values that result from the dependent variable, which is usually y, after you have substituted the domain. It is the result of the y values you get after having substituted all the x values. So it is all real numbers.

The domain of a function is the set of all the possible values that result from the independent variable, which is usually x. It is the result of all possible x values that make the function actually "work" and will lead to real y values. So it is all real numbers greater than 0. It cannot be zero and it has to be positive.
