Anil Kumar explains how to determine the average rate of change for different intervals on a downward-opening parabola. He guides viewers through analyzing secant lines for intervals 0 to 1, 1 to 2, 2 to 3, and 3 to 4, identifying positive rates of change for the first three intervals and a negative rate for the last interval.
