Answer:
Step-by-step explanation:
Given the function f(x)=x-3
So we want to know the value of the function when
1. x=1
Then, f(x) =x-3
Let substitute x=1
f(1)=1-3
f(1)=-2
2. x=2
Then, f(x) =x-3
Let substitute x=2
f(2)=2-3
f(2)=-1
3. x=4
Then, f(x) =x-3
Let substitute x=4
f(4)=4-3
f(4)=1
4. x=5
Then, f(x) =x-3
Let substitute x=5
f(5)=5-3
f(5)=2
5. x=8
Then, f(x) =x-3
Let substitute x=8
f(8)=8-3
f(8)=5
f(x)=x-3
x. 1 2 4 5 8
f(x). -2 -1 1 2 5
