Since the denominator must not be equal to zero, we find the value of x that will make the denominator zero, so that it will not be included in the domain: X + 1 = 0 --> X = -1. SO, THE DOMAIN IS SET OF ALL REAL NUMBERS EXCEPT -1. For the range, we see that the equation will never be equal to zero, since the numerator is 1. So, the range is set of all real numbers except 0.
