To find the vertex of the quadratic function that represents the inverse of a graphed square root function, we first need to understand the relationship between square root functions and their inverses.

A square root function in the standard form is typically expressed as:

\[ y = \sqrt{x} \]

Its inverse can be found by swapping the \(x\) and \(y\) variables and solving for \(y\):

\[ x = \sqrt{y} \implies y = x^2 \]

The function \(y = x^2\) is a quadratic function. The vertex of this quadratic function occurs at the coordinate (0, 0), since it opens upwards and is symmetrical about the y-axis.

Therefore, the vertex of the related quadratic function representing the inverse of the square root function is:

\[ (0, 0) \]
