Answer

The domain is all real numbers besides 0. The range is all real numbers besides 0.

Work Step by Step

Because the function is a fraction, for it to be valid, we need the denominator to not equal zero. Because s is in the denominator, zero is not within the domain of s. All real numbers are included in the range with the exception of 0. Because the numerator will never equal zero, 0 is not included in the function's range.
