Answer:
b
Step-by-step explanation:
The red graph is the black graph horizontally translated to the right.
Given f(x) then f(x + a) is a horizontal translation of f(x)
• If a > 0 then shift to the left of a units
• If a < 0 then shift to the right of a units
Here the shift is 3 units to the right, thus
y = f(x - 3) → b
