Hi Christine;
The domain is all the values of x this equation can accommodate.  There are no limitations on x, such as if it is positioned within a denominator thereby eliminating x=0.
DOMAIN...(-infinity, +infinity)
f(x)=y is the range.  This is all possible values of y.  Since there is nothing limiting x, there is nothing limiting its equation results...
RANGE...(-infinity, +infinity)
What are the other problems?
