Answer 1

Answer: 2

Explanation:

In functions, we get to know the domain and range. Or we can name them inputs and outputs. We are given that our output is 4 which means the input is the tail of the arrow pointing at 4, which is 2 from the diagram. So the answer is 2

Answer 2

The answer of f(x)=4 is 0
