Answer: 16 (choice C)
========================================================
Explanation:
The second table shows that g(2) = -3. Simply locate 2 in the x column, then read directly across to determine its output.
The notation f( g(2) ) then updates to f( -3 ) after replacing g(2) with -3.
Then we use the first table to see that f(-3) = 16
Ultimately, f( g(2) ) = 16
