Exploring the Curve of Quadratic Functions in Vertex Form

Interact with the app below by dragging the TWO LARGE POINTS. [br]Then answer the questions that follow.
Suppose you graph the quadratic function [math]y=a\cdot\left(x-h\right)^2+k[/math]. [br][br]What does the parameter [math]k[/math] do to the graph? Explain.
