Answer
Domain = (negative infinity, infinity)
Range = (negative, inifinity)
Work Step by Step
Problem 23 shows a line that stretches infinitely in domain and range. This signifies that domain cannot be closed and that it has no set value. Because the domain stretched on infinitely, our answer must also be infinite. This applies to the range as well.
Domain= (negative infinity, infinity)
Range= (negative infinity, infinity)
The reason we use parenthesis is to signify that the domain/ range is not closed off. Instead, it is open, because the function if forever increasing.
