Which of the following functions describe the graph shown in the below figure.
 y = x+ 1–2
 y = x– 1–1
 y = x+ 1–1
 y = x–1– 1
Correct Option : B
Here from graph for x = 1, y = – 1
Checking the same from options.
From option (a)
for x = 1
y = 1 + 1  2
= 2  2 = 0
∴ Option (a) is wrong
From option (c)
for x = 1
y = x + 1  1
=1 + 1  1 = 1
∴ Option (c) is wrong.
