We did another Desmos activity today about expanding our ability to discuss key features of any polynomial graph, not just parabolas. We observed that terms like “y-intercept” and “zero” still apply, but terms like “vertex” and “axis of symmetry” no longer work when there are multiple turning points on a polynomial graph. So instead we now have terms like “local maximum,” “local minimum,” and “inflection point.”
We haven’t finished our exploration yet, so the homework linked below is not due just yet. Take a look at it, though!
