To determine the vertex of the quadratic function related to the square root function \( h(x) \), we generally look for the point on the graph where the function changes direction, which corresponds to the vertex of the quadratic function.
In a standard quadratic function of the form \( y = ax^2 + bx + c \), the vertex can be found using the formula \( x = \frac{-b}{2a} \) to find the x-coordinate and then substituting that back into the function to find the y-coordinate.
However, since I cannot see the graph you are referring to, I cannot provide you with specific coordinates for the vertex.
If you can describe the graph, mention the values where the curve changes direction or its highest or lowest point, or give any specific coordinates from the graph, I would be able to help you further in identifying the vertex.
