To explore function composition on Desmos Calculator https://desmoscalculator.net/graphing-calculator/ start by entering two functions, such as f(x) = x^2 and g(x) = 2x + 1. You can then create the composite function h(x) = f(g(x)) = (2x + 1)^2 and graph it. The calculator will display the curve of the composed function, showing how applying one function after another transforms the input. Using sliders for coefficients in either function allows you to adjust the parameters interactively and observe how the composition changes in real time.
