A function is a relation in which the members of the domain (x-values) do not repeat. So, for every x-value there is only one y-value that corresponds to it.
The room is 5 inches long in the drawing.
Step-by-step explanation:
Given,
Scale drawing used by Kenneth;
1 inch = 4 feet
Ratio of scale = 1:4
Actual length of room = 20 feet
Let,
x be the length in drawing
Ratio of actual length = x:20
Using proportion
Scale ratio :: Actual ratio

Product of mean = Product of extreme

Dividing both sides by 4

The room is 5 inches long in the drawing.
