Suppose 
To obtain the graph of 
Upwards
CORRECT
Downwards
To the right
To the left
Up and right
Explanation
There are four shifts of the graph y = f(x):
y = f(x) + c shifts the graph c units upwards.
y = f(x) – c shifts the graph c units downwards.
y = f(x + c) shifts the graph c units to the left.
y = f(x – c) shifts the graph c units to the right.
