Answer:
D
Step-by-step explanation:
with this functional definition y can never have a negative value.
so, A and C are automatically out.
and then find some core points (like x = 0 and y = 0).
for x = 0 we get y = 3. ok, that fits to both B and D.
for y = 0 x must be 3.
and that leaves only D as right answer.
