Use the left and right arrow keys to move between steps. Practice next in the Exponential Lab. Exponential growth curves are purple, decay curves and linear comparisons are teal, and asymptotes are gold dashed lines. Health examples use made-up practice numbers and are not dosing guidance. Animations loop so you can watch them as many times as you like.
