The linear function `f: D -> R,\ f(x) = 6 - 2x` has range `text([−4, 12]).`
The domain `D` is
`A`
| `12` | `= 6 – 2x` |
| `x` | `= – 3` |
| `- 4` | `= 6 – 2x` |
| `x` | `= 5` |
`:. x in [– 3, 5]`
`=> A`
The linear function `f: D -> R,\ f(x) = 5 - x` has range `[−4, 5).`
The domain `D` is

| `x` | `= 0` | `x` | `= 9` |
| `text{(non-inclusive)}` | `text{(inclusive)}` | ||
`:. x ∈ (0, 9]`
`=> A`
