Option D: 14 is the right answer
Step-by-step explanation:
In order to find the value of given expression we have to put the given value for f in the expression
Given expression is:
We have to find the value of expression on f=3
So,
putting f=3 in expression
The value of given expression at f=3 is 14
Hence,
