Given:
Given, y = |x|
If y = x
x 0 1 2
y 0 1 2
If y = -x
x 0 -1 -2
y 0 1 2
(i) y = |x – 1| + 1
y = x – 1 + 1
y = -x + 1 + 1 = x
x -1 0 1
y 3 2 1
(For y = 2 - x)
(ii) y = |x + 1| – 1
y = x + 1 – 1 = x
y = -x - 1 – 1
y = -x – 2
y = – (x + 2)
x 0 1 2
y -2 -3 4
(iii) y = |x + 2| – 3
y = x + 2 – 3 ⇒ x – 1
y = -x – 2 + 3 = 1 – x
y = -(x – 1)
x 0 1 2 3
y 1 0 -1 -2
