Question

You have 7 cups of flour. It takes 1 cup of flour to make 24 cookies. The function () = 24 represents the number of cookies, , that can be made with cups of flour. What domain and range are reasonable for the function?

a. The domain is 0 ≤ ≤ 7, the range is 0 ≤ () ≤ 168
b. The domain is 0 ≤ () ≤ 168, the range is 0 ≤ ≤ 7
c. The domain is 24 ≤ () ≤ 168, the range is 1 ≤ ≤ 7
d.The domain is 1 ≤ ≤ 7, the range is 24 ≤ () ≤ 168

Answer 1

First, we must remember the following:

Domain = x-axis

Range = y-axis

x-axis= independent variable
y-axis= dependent variable

With this in mind we must identify the x and y:

x: The cups of flour as the amount of cookies depends on the amount of flour used.

y: The amount of cookies

Thus, using this information the correct answer would be:
A. The domain is 0 ≤ ≤ 7, the range is 0 ≤ () ≤ 168

Hope this helps c:
