Given the parent function $$ f(x) = \sqrt{x} $$ , write the ...

Question Analysis
This question tests the understanding of function transformations, specifically reflection over the x-axis and vertical shift.

Key Concept Explanation
A reflection over the x-axis means that the function is flipped vertically. A shift down by 7 units means that the entire graph is moved 7 units downwards.

Step-by-step Solution
1. Start with the parent function:
2. Apply the reflection over the x-axis:
