The graph of the square root function is typically \( f(x) = \sqrt{x} \), which has a vertex at the origin point (0,0).
To find the inverse of this function, we start with \( y = \sqrt{x} \) and solve for \( x \):
- Square both sides: \( y^2 = x \).
- Rearranging gives us the inverse function: \( x = y^2 \) or \( f^{-1}(x) = x^2 \).
The graph of this inverse function, \( f^{-1}(x) = x^2 \), is a quadratic function.
For the quadratic function \( f(x) = x^2 \), the vertex is at the point (0,0).
Thus, the vertex of the related quadratic function is:
\[ (0, 0) \]
