Substitute the number of passengers into x and then calculate.
130, 140, 160, and 180
The range is the set of all possible values that the function can take as its input (argument), which varies over its domain. To show the cost of renting a van for a day with different number of passengers, we can make a table.
| x | 100+5x | C(x) |
|---|---|---|
| 6 | 100+5 * 6 | 130 |
| 8 | 100+5 * 8 | 140 |
| 12 | 100+5 * 12 | 160 |
| 16 | 100+5 * 16 | 180 |
The only numbers that are in the range are 130, 140, 160, and 180.
