Draggable points that create an equation. Equation populates a table

I want the students to drag the points to create ANY parabola that could model the hammock in the graph. I would like the equation of their parabola to populate the table (or anywhere tbh) so students can find the vertex of their specific parabola.

The easiest solution is to display the equation on the graph. Create a point, say at (0,-3), with the label y=${a}(x-${h})^2+${k} inside of backticks, and you’ll see the formula on the graph. You can hide the point so you only see the equation.

great thanks so much!
