parabola net 1

This exploration [url=https://www.geogebra.org/m/ptek2nwg]follows another activity[/url] about using curve stitching to introduce parabola as the shape of a quadratic graph. [br][br]In this activity, you may compare parabolas / quadratic graphs generated by curve stitching along two fixed lines. [br][br]For beginning learners of quadratic graphs, a simple activity could be identifying changes in the coefficients among a set of graphs (or family of graphs / functions). [br][br]More advanced learners may explore the relation between the coefficients: describe and test the relation, or even prove it.[br][br]You may try [url=https://www.geogebra.org/m/ry4nc2jh]another extended activity[/url] where the generating lines can also be varied.
