(a)

Karen $\"\"$ s copies charge for every minute $\"\"$ .

No.of minutes are $\"\"$ and the value of $\"\"$ .

Cost of the using the scanner for $\"\"$ minutes is $\"\"$ .

Graph :

Draw the graph for the function $\"\"$ .

$\"\"$

(b).

The function is $\"\"$ .

The domain of the function $\"\"$ is $\"\"$ .

The range of the function $\"\"$ is positive multiples of $\"\"$ .

$\"\"$

(c)

Graph :

Draw the graph for the inverse function $\"\"$ .

$\"\"$

Observe the graph :

The graph of the inverse function is reflection of the graph of the function with respect to the line $\"\"$ .

$\"\"$

(d)

The Domain of inverse function is the range of the function $\"\"$ .

Domain of the inverse function is positive multiples of $\"\"$ .

Range of the inverse function is $\"\"$ .

(e)

A real time example is time taken by the scanner to take particular number of copies.
