Best ResponseYou've already chosen the best response.1\[12x+24 \ge 0\] solve for x for the domain, the range is all the y values, so that should be somewhat obvious \[f \in \mathbb{R}: f \ge 0\]

Best ResponseYou've already chosen the best response.0would this be 1 way to do it? y = SqrRoot (12x + 25) 12x+24>=0 giving a domain Real values >= 2. The range of y is y>=0.
