To find:
A function that models area in terms of width.
Answer to Problem 1P
Solution:
The area of the building modeled by the function
Explanation of Solution
The model we want is a function that gives the area of the rectangular building.
For the rectangular building,
There are two varying quantities: Length and Width.
But the function we want depends on the width w.
We must express the length in terms of its width w. Because the length of the building is three times as long as it is wide. If we let length be l, then we have,
The model is the function A that gives the area of the rectangular building for any width w.
Thus, the area of the building modeled by the function
Final statement:
The area of the building modeled by the function

- An outpatient operating room charges each patient a fixed amount per surgery plus an amount per minute for use. One patient was charged 250 for a 30-minute surgery and another patient was charged 450 for a 90-minute surgery. Determine the linear function that would be used to compute the charges. Use the function to determine the charge when a patient has a 45-minute surgery.arrow_forwardWhat is the difference between the input and the output of a function?arrow_forwardHow do you find the value of a function?arrow_forward
