Answer:
f(1/3) = 1
Explanation:
Given
f(n)=3n
We have to find f(1/3).
In order to find the value of the given function at a point, we put the value in the function where the variable is used.
i.e. to find f(2) for f(x); x will be replaced by 2 in the function. Similarly to find f(1/3), we will replace n by 1/3 in the function.
So to find
f(1/3)=3* 1/3
=1
So, the value of f(1/3) is 1 ..
