Kaip apskaičiuoti Exponential Growth
Kas yra Exponential Growth?
Exponential growth and decay describe processes where the rate of change is proportional to the current value. Growth occurs when the rate is positive (population growth, compound interest, viral spread). Decay occurs when negative (radioactive decay, drug elimination, cooling). The continuous model uses the natural exponential function P(t) = P₀ × e^(rt).
