$\"\"$

\

The function is $\"\"$ .

\

$\"\"$

\

First graph the parent function.

\

Parent function of $\"\"$ is $\"y$ .

\

Compare $\"y$ with $\"\"$ .

\

Here $\"\"$ .

\

where $\"\"$ , so the graph of $\"y$ passes through $\"\"$ , $\"\"$ , $\"\"$ .

\

$\"\"$

\

Next graph the original function using transformation $\"\"$ .

\

Graph of the original function shift two units down.

\

The graph of $\"\"$ passes through $\"\"$ , $\"\"$ and $\"\"$ .

\

Graph :

\

1. Draw a coordinate plane.

\

2. Plot the coordinate points.

\

3. Then sketch the graph, connecting the points with a smooth curve.

\

$\"\"$

\

Observe the above graph :

\

Domain of the function is $\"\"$ .

\

Range of the function is $\"open$ .

\

Horizontal asymptote of the function is $\"y$ .

\

$\"\"$

\

$\"\"$

\

Domain of the function is $\"open$ .

\

Range of the function is $\"open$ .

\

Horizontal asymptote of the function is $\"y$ .
