| Domain | the set of all possible x-values which will make the function "work", and will output real y-values. All the values that go into the function. |
| continuous data | quantitative data that can be measured |
| range | difference between lowest and highest value |
| coefficient | A number used to multiply a variable. Example: 6z means 6 times z, and "z" is a variable |
