Question

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

situation.
$) = 30
Of(n) = 120

Answer 1

`f(n) = (n)/(3)`

Explanation:

Recall that:

`3ft = 1 \: yd`

This implies that:

`6ft = 2yds`

`9ft = 3yds`

In general:

`n \: ft = (n)/(3) \: \: yds`

We can therefore write the function rule:

`f(n) = (n)/(3)`
