Question

A bakery's production is modeled by function f(x), where f(x) is the number of donuts made in a day and x is the number of bags of flour needed. Choose the ordered pair that represents a possible domain and range of the function.

(−1, 15)
(5, 92.75)
(10, 100)
(−5, 110.5)

Answer 1

(10,100) is the correct answer

Answer 2

The correct option is 3. The possible domain and range of the function is (10, 100).

Explanation:

It is given that a bakery's production is modeled by function f(x), where

f(x) = The number of donuts made in a day

x = The number of bags of flour needed.

The number of donuts made in a day and the number of bags of flour needed can not be a fraction value of a negative number. So, the values of x and f(x) can not defined by negative or decimal numbers.

In ordered pair (-1,15), the value of x is negative, so option 1 is incorrect.

In ordered pair (5,92.75), the value of y is in decimal, so option 2 is incorrect.

In ordered pair (10,100), both coordinates are positive integers, so option 3 is correct.

In ordered pair (-5,110.5), the value of x is negative and the value of y is in decimal, so option 4 is incorrect.

The possible domain and range of the function is (10, 100). Therefore the correct option is 3.
