To determine the vertex of the quadratic function related to the square root function graphed, we need to understand that the vertex typically represents the minimum or maximum point of the quadratic function.
Given that the curve "h(x)" is described to curve up from -2, this suggests that the graph has a minimum point at (0, -2), where it turns from decreasing to increasing.
Based on the provided options, the most appropriate choice for the vertex of the related quadratic function is:
(0, −2)
This indicates that the vertex of this curve is at the point (0, -2).
