Answer:
f(n) = n/36
Step-by-step explanation:
The length of a string is given in yards, is a function f(n) of the length n in inches.
We have to write a function rule for this situation.
∵ 36 inches = 1 yard
∴ 1 inch = 1/36 (yard)
∴ n inches = n/36
and function representing the length will be
f(n) = n/36
