Exponential Growth & Decay Exponential Growth (Appreciation) is when something increases at a constant rate over time. Exponential Decay (Depreciation) is when something decreases at a constant rate over time. a(1 ± r) t a = original amount r = rate (changed to a decimal) t = time passed *Add for Growth *Subtract for Decay
