Answer:
- f(-1) = -6
- f(0) = -5
- f(1) = -4
- f(2) = -3
- f(5) = 0
- f(8) = 3
Explanation:
1) Substitute x = -1 into f(x) = x - 5
- f(x) = x - 5
- f(-1) = (-1) - 5
- f(-1) = - 1 - 5
- f(-1) = -6
2) Substitute x = 0 into f(x) = x - 5
- f(x) = x - 5
- f(0) = (0) - 5
- f(0) = 0 - 5
- f(0) = -5
3) Substitute x = 1 into f(x) = x - 5
- f(x) = x - 5
- f(1) = (1) - 5
- f(1) = 1 - 5
- f(1) = -4
4) Substitute x = 2 into f(x) = x - 5
- f(x) = x - 5
- f(2) = (2) - 5
- f(2) = 2 - 5
- f(2) = -3
5) Substitute x = 5 into f(x) = x - 5
- f(x) = x - 5
- f(5) = (5) - 5
- f(5) = 5 - 5
- f(5) = 0
6) Substitute x = 8 into f(x) = x - 5
- f(x) = x - 5
- f(8) = (8) - 5
- f(8) = 8 - 5
- f(8) = 3
