Hint: For what values of will cause the denominator be equal to 0? Remember, you can't divide by 0.

i know this thread is kinda done with, but cant the domain really just be any real number? in algebra we know that the domain of a function can be any real number, so long as it has only one range, but thats besides the point of the fact that shouldnt the answer be any real number?
