Sagot :

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

[tex]f(n)=3n[/tex]

Therefore, the function rule for this situation is:

[tex]f(n)=3n_{}[/tex]

ANSWER: D

[tex]f(n)=3n[/tex]
