$\"\"$

The vertical shift in the graphs of $\"\"$ is represented as Vertical shift c units upward: $\"\"$ .

The vertical shift in the graphs of $\"\"$ is represented as Vertical shift four units upward: $\"\"$ .

The function is $\"\"$ .

The points $\"\"$ are lie on the graph f.

To graph $\"\"$ is shift four units up (add four units to y - coordinate) the $\"\"$ , So the points $\"\"$ are lie on the required graph $\"\"$ . $\"\"$

Function $\"\"$ graph is
