Step-by-step explanation:
Step 1: Define
Identify
[Function] f(x) = x - 5
f(-1) is x = -1 for function f(x)
f(0) is x = 0 for function f(x)
f(1) is x = 1 for function f(x)
f(2) is x = 2 for function f(x)
f(5) is x = 5 for function f(x)
f(8) is x = 8 for function f(x)
Step 2: Evaluate
f(-1)
- Substitute in x [Function f(x)]: f(-1) = -1 - 5
- Subtract: f(-1) = -6
f(0)
- Substitute in x [Function f(x)]: f(0) = 0 - 5
- Subtract: f(0) = -5
f(1)
- Substitute in x [Function f(x)]: f(1) = 1 - 5
- Subtract: f(1) = -4
f(2)
- Substitute in x [Function f(x)]: f(2) = 2 - 5
- Subtract: f(2) = -3
f(5)
- Substitute in x [Function f(x)]: f(5) = 5 - 5
- Subtract: f(5) = 0
f(8)
- Substitute in x [Function f(x)]: f(8) = 8 - 5
- Subtract: f(8) = 3
