Using the table below, evaluate whether a monkey's age in years is a function of its height in inches.

Height (inches) Age (years)

30 2

28 3

36 4

36 5

44 6

A.

Yes, because there are no two monkeys in this table with the same age.

B.

Yes, because each monkey's height is bigger than its age.

C.

Prissy · Answer 1

Correct answer is D.

For one value of x function y=f (x) cannot have two values for y.

Since monkey's age in years is a function of its height, we have function a=f (h), where a is monkey's age in years and h is its height.

For one value of h function a=f (h) cannot have two values for a. But for the height of 36 inches, we have two values for a, 4 and 5. Therefore, function a=f (h) cannot exist.
