Answer:
C
Step-by-step explanation:
Given f(x) then f(x) + c is a vertical translation of f(x) by c units
• If c > 0 then shift c units up
• If c < 0 then shift c units down
The red graph is a vertical translation f(x) of 3 units down
Thus
y = f(x) - 3 ( add 3 to both sides )
y + 3 = f(x) ← equation of red graph
