Answer:
3
Step-by-step explanation:
This is very simple.
f(x) means the function of x.
The question means,
"What is the function result if 2 was x"
The table does not show how it works, but it gives the result directly.
In the table, in the "x" column, there is a 2.
In the "f(x)" column, there is a 3 next to the number 2.
