To explore derivatives on Desmos Calculator, start by entering a function such as <code data-start=”252″ data-end=”270″>y = x^3 – 2x + 1. You can then type <code data-start=”290″ data-end=”294″>y’ or use the derivative feature to plot the slope of the function at every point. The resulting graph shows how the rate of change varies along the curve, making it easy to identify where the function is increasing, decreasing, or has a maximum or minimum.
