| How do you determine if a graph is a function? | vertical line test |
| How do you determine if a graph is one-to-one? | It passes both vertical and horizontal line tests |
| Determine if y = square root of x - 7 is a function and if it is one-to-one. | Yes it is a function and it is one-to-one |
