StatementThe second one is:
- The range of is
- The square of any real number is non-negative (in other words the range can't contain any negative numbers)
- Every non-negative number is the square of its own square root (in other words, every non-negative number is included in the range because there will always exist a corresponding element in the domain, namely, its square root)StatementI hope that is what you wanted.
- The range of ... is the set of all non-zero real numbers.
- (in other words, the reciprocal function is its own inverse. So, since the domain of is all non-zero real numbers the range will also be all non-zero real numbers)
