Question

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

A.f(n) = 12n
B.f(n)=1/3n
C.f(n)=n/12
D.f(n) = 3n

Answer 1

D.f(n) = 3n

Explanation:

The function rule for this given situation is shown below;

Given that

The length of the field in feet would be f(n) of the length n in yards

Now as we know that

1 yard = 3 inches

So

f(n) = 3n

Hence, the option d is correct
