Inflexion Points and Concavity

This GeoGebra applet may be used to explore points of inflexion and concavity. Choose domain using sliders Left and Right. Input a function. The concave up parts are graphed in red and concave down in blue. Slider c may be used to determine/estimate inflexion points. For more on concavity check my online book "Flipped Classroom Calculus of Single Variable" https://versal.com/learn/vh45au/
