Answer: Choice C
f(x) = x+5
===========================================
Explanation:
The input x = -3 has 5 added to it to get x+5 = -3+5 = 2
The diagram shows the "-3" in the input oval pointing to "2" in the output oval.
Through similar steps, we have the input -2 map to the output 3. Also, the input 0 points to the output 5.
The input -5 should map to 0, but 0 isn't in the output list. So we ignore -5 in the input oval.
