Bilangan real = {1,2,3,4,5,...}

1. f(x) = |x + 2|
f(1) = |1 + 2| = |3| = 3
f(2) = |2 + 2| = |4| = 4
f(3) = |3 + 2| = |5| = 5
....
y = {3,4,5,6,7,...}

2. f(x) = |x - 3|
f(1) = |1 - 3| = |-2| = 2
f(2) = |2 - 3| = |-1| = 1
f(3) = |3 - 3| = |0| = 0
f(4) = |4 - 3| = |1| = 1
...

3. f(x) = |2x + 3|
f(1) = |2(1) + 3| = |5| = 5
f(2) = |2(2) + 3| = |4 + 3| = 7
f(3) = |2(3) + 3| = |6 + 3| = 9
....

4. f(x) = |-2x + 5|
f(1) = |-2(1) + 5| = |-2 + 5| = 3
f(2) = |-2(2) + 5| = |-4 + 5| = |1| = 1
f(3) = |-2(3) + 5| = |-6 + 5| = |-1| = 1
...

5. f(x) = |1/2 x - 2/3|
f(x) = |3/6 x - 4/6|
f(x) = |(3x - 4)/6|

f(1) = |(3(1) - 4)/6| = |(3 - 4)/6| = |-1/6| = 1/6
f(2) = |(3(2) - 4)/6| = |(6 - 4)/6| = |2/6| = 1/3
f(3) = |(3(3) - 4)/6| = |(9 - 4)/6| = |5/6| = 5/6
...
