What is the domain and range for the following function and its inverse? f(x) = -x + 5
iren2701 [21]

Answer:

Domain: \mathbb{R}

Inverse: f^{-1}(x) = -x + 5

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,

f^{-1}(x) = -x + 5

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 ...
