Question Analysis
This question involves identifying the horizontal shift of a square root function from its graph. The main focus is on using the vertex (starting point) of the graphed function to find the missing horizontal shift value in the function equation.

Key Concept Explanation
Vertex of Parent Square Root Function: The parent function has a vertex (starting point) at .
Horizontal Shift Rule: When a square root function is shifted horizontally by h units to the right, its equation becomes . The vertex of this shifted function is —the y-coordinate stays 0 (no vertical shift), and the x-coordinate equals h.

Step-by-step Solution
1. Identify the vertex of the graphed function: The graph starts at , so the vertex is
