Domain and Range - Definition & Finding Graphically
![Graph of y=1/(x^2-1) with domain [-5,5] and range [0, infinity).](https://d20khd7ddkh5ls.cloudfront.net/desmos-graph-59.png)
Two motorcycles are being launched into space. They are going to start at the bottom of a ramp and go up straight to outer-space where they will travel in the line they were launched from for infinity. The two ramps are facing each other so they look like the graph above. What is the domain and range of the graph?
