This tutorial explores a quadratic function in standard form (y = ax^2 + bx + c) using sliders on the TI-Nspire app. It creates a graph window, inserts three sliders to control the values of a, b, and c, links the sliders to the quadratic function, and allows manipulating the sliders to update the graph.
