The length of a field in yards is a function f(n) of the length n in feet. Write a function rule for th

lara [203]

Answer:

$f(n) = \frac{n}{3}$

Step-by-step explanation:

$3ft = 1 \: yd$

This implies that:

$6ft = 2yds$

$9ft = 3yds$

In general:

$n \: ft = \frac{n}{3} \: \: yds$

We can therefore write the function rule:

$f(n) = \frac{n}{3}$
