Inverse: 
Step-by-step explanation:
Since this is a linear function, the domain and range is simply the set of real numbers.
The inverse is obtain by switching the places of x and y, then solving for y.
Here,
y = -x + 5
So switching x and y,
x = -y + 5
Solving for y again,
y = -x + 5
Thus,

Answer:
4424 books
Step-by-step explanation:
After the revenue from each book pays for its own cost, it can contribute to the payment of the fixed costs. That "contribution margin" is ...
$25.50 -11.25 = $14.25
If each book sold contributes that much to the recovery of fixed costs, then the total number of books that must be sold to break even is ...
$63,042/($14.25/book) = 4424 books
4424 books must be produced and sold so production costs equal sales.
