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

D.f(n) = 3n

Step-by-step 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

step-by-2step explanation:

use this formula:

p(a\b) = p(a and b)/p(b).
