Question
If 
is defined by 
Hint:
In this question we have to find the value of n where f(n) will be greater than 2. From the given function two options will not be considered as in both the cases f(n) will be 2 and o. Now considering the third case we have to find the value of n.
The correct answer is:
For f(n)
, 
So, f(n)
we will consider, f(n)=10-n, if n=3k+1
