In either case, the domain is the set of values of for which the function is defined. Notice that you have a variable in the denominator of your function. Since division by zero is undefined, what does that tell you about the values that can take on?
The range will be all of the possible values of . For , note that can never be zero; what does that tell you about the possible values of ?
