The graph shown in the image appears to resemble a square root function, specifically part of the graph of $y = \sqrt{x}$, but it has been reflected vertically and shifted downwards.

Step-by-step identification of transformations:

1. Parent function: The general square root function is $y = \sqrt{x}$, which starts at the origin and curves upward to the right.

2. Reflection: In this case, the curve is reflected across the x-axis, indicating a vertical reflection. This introduces a negative sign in front of the square root function, resulting in $y = -\sqrt{x}$.

3. Vertical shift: The graph appears to be shifted down. Instead of starting at the origin (0, 0), it seems to begin around (0, -5). This means the graph is shifted down by 5 units, giving $y = -\sqrt{x} - 5$.

Final equation:

The equation for the graphed function, based on these transformations, is: $y = -\sqrt{x} - 5$

Would you like further details on any part of this process?

Here are some related questions to think about:

1. What are other possible transformations of the square root function?
2. How does reflecting a function across the x-axis change its graph?
3. What happens when a function is shifted vertically or horizontally?
4. Can this transformation be applied to other parent functions?
5. How can you determine the range of the function based on its transformation?

Tip: Always analyze the starting point and direction of a graph to identify shifts and reflections correctly!
