$\"\"$

The function is $\"\"$ .

The function $\"\"$ is the product of the functions $\"\"$ and $\"\"$ .

Therefore the damping factor is $\"\"$ .

Graph:

Graph of the function $\"\"$ and damping factor $\"\"$ .

$\"\"$

Observe the graph :

As $\"\"$ tends to $\"\"$ , the amplitude of the function decreases and $\"\"$ tends to $\"\"$ , the amplitude of the function increases .

Therefore, as $\"\"$ tends to $\"\"$ , the amplitude of the function decreases from right side.
