Question

The length of a field in yards is a function f(n) of the length n in feet. Write a function rule for this situation. A. f(n) = 1/3nB. f(n)= n/12 C. f(n) = 12nD. f(n)= 3n

Answer 1

Given that the length of a field in yards is a function f(n) of the length n in feet.

Let's write a function rule for this situation.

Apply the unit for conversion, where:

1 yard = 3 feet

Hence, to write the length of the field in yards as a function of the length in feet, we have:

Number of yards = 3 feet

`f(n)=3n`

Therefore, the function rule for this situation is:

`f(n)=3n_{}`

ANSWER: D

`f(n)=3n`
