6.4 Exponential Growth and Decay Calculus 6.4 EXPONENTIAL GROWTH AND DECAY In many applications, the rate of change of a variable y is proportional to the value of y. If y is a function of time t, we can express this statement as Example: Find the solution to this differential equation given the initial condition that yy=0 when t = 0. EX #1: Solve the differential equation. 2. EX #2: Solve the differential equation. 3 EXPONENTIAL GROWTH AND DECAY MODELS. If y is a differentiable function of t such that y > 0 and. for some constant k, then. C is the initial value of y, and k is the proportionality constant. Exponential growth occurs when k > 0, and exponential decay occurs when k < 0.
