Zooming In on a graph

An experiment with using Desmos on a phone.graph match - big derivative puzzle

The idea is to look at the properties of amount functions (e.g. \(f(x)\)) and their rate functions (the derivative functions, e.g. \(f'(x)\)).

A key idea is that the derivatives of \(f(x)\) and \(p_n(x)\) take on the same values at \(x=a\).
