$\"\"$

The function is $\"\"$ .

(a).

$\"\"$ .

$\"\"$

Therefore, inverse of the function $\"\"$ is $\"\"$ .

$\"\"$

(b).

(1).Draw the coordinate plane.

(2).Graph the functions $\"\"$ and $\"\"$ on the same set of coordinate axis.

Graph :

$\"\"$ .

$\"\"$

(c).

Relationship between the graphs :

Observe the graph :

The functions $\"\"$ and $\"\"$ are reflections of each other across the line $\"\"$ .

$\"\"$

(d).

Domain and range of $\"\"$ :

The domain of $\"\"$ is set of all real numbers $\"\"$ .

The range of $\"\"$ is set of all real numbers $\"\"$ .
