Answer:
B.
Explanation:
You can easily read the point (2, 0).
Let's try each equation with point (2, 0).
A.
y = √x + 2
y = √2 + 2
y = 2.41
This is point (2, 2.41), not (2, 0), so this equation is not it.
B.
y = √(x - 2)
y = √(2 - 2)
y = 0
This is point (2, 0), so this equation may be it.
C.
y = √x - 2
y = √2 - 2
y = -0.586
This is point (2, -0.586), not (2, 0), so this equation is not it.
Answer: B.
