Question

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

Answer 1

Given:

The length of field is n yards.

The length of a field in feet is a function f(n).

To find:

The function rule for this situation.

Solution:

We know that,

1 yard = 3 feet

Using this conversion, we get

n yard = 3n feet

The length of field is n yards. So, the length of the field is 3n feets.

The length of a field in feet is a function f(n). So,

$f(n)=3n$

Therefore, the required function rule for this situation is $f(n)=3n$.
