Question

The relationship between the side length of a square and its perimeter is expressed in function notation below.

Perimeter(side length) = 72 inches

Which of the following is the best translation of this equation?

A. The perimeter of the square (which depends on its side length) is 72 inches.
B. The side length of the square (which depends on its perimeter) is 72 inches.
C. The area of the square (which depends on its side length) is 72 inches.

Answer 1

Function notation for f(x) would be f is a function of x, meaning f is dependent on x. With this, you can eliminate B, as your f is perimeter and your x is length and B states your side length is dependent on your perimeter when it should be the other way around. To decide between A and C, just see that your function is determining perimeter, not area, eliminating C. This makes your answer A, as the notation is stating that your perimeter in relation to your side length is 72 inches.
