I have the opportunity to introduce (or re-introduce) quadratics to students fairly regularly, and I'm eager to incorporate this understanding! I've often highlighted the symmetry of the quadratic formula, though usually we get there via completing the square, rather than this translation approach.

I desperately wish students got more practice with function transformations. It's a powerful tool that far too many students leave high school without understanding.
