For this case we are going to do a small step-by-step study of the given functions.

1) Option A is discarded because by substituting x = 0 in the given equation, the result is positive, which does not agree with the graph.

2) Option B is discarded because when substituting x = 0 in the given equation, the root is negative and the result will be an imaginary number.

3) Option C is discarded because when substituting x = 0 in the given equation, the result is positive, which does not agree with the graph.

4) Option D is the correct one:

y = √(x) - 3
When replacing x = 0 we have:

y = √(0) - 3

y = 0-3 y = -3
This result agrees with the graph shown.

Answer:

y = √(x) - 3
Option D.
