Finding Rate of Change at Points
In this activity, try to put A, B and C at three places where you can estimate the rate of change of the function shown. You might look for places where the rate of change is zero, but also find places where it is positive or negative and you have to estimate how positive or negative. Once you have placed your points, click check to see how you did. Clicking next gets you the next function to try.
There are 6 functions to try here. I'd suggest a derivative sketching activity next: https://www.geogebra.org/m/nUcgDV3m
