WebSep 7, 2024 · Many systems exhibit exponential growth. These systems follow a model of the form y = y 0 e k t, where y 0 represents the initial state of the system and k is a positive constant, called the growth constant. Notice that in an exponential growth model, we have (6.8.1) y ′ = k y 0 e k t = k y.
