Answer: y > 0
Explanation: you can identify the range or limit of this equation by either looking at the graph or understanding the equation logically.
Looking at the graph, you can see to the left of the Y axis, the graph is approaching but not touching Y = 0. This means that Y = 0 is a limit to this equation and that the graph will not cross this line.
Or we can think about it logically. If we keep multiplying by 2 over and over, a value will keep getting bigger to infinity. That's the right side of this graph. Then for x < 0, that represents dividing by 2 over and over. That value will only ever get smaller and smaller. But never reach zero. It's like folding a paper in half forever.
