This chapter describes a wide variety of exponential behavior models, including population growth, radioactive decay, charging and discharging of capacitors, inflation and interest, and armies at war. The rate of change of a variable, whether positive (as it grows) or negative (as it decays), ...
exponential growth or decay function is a function that grows or shrinks at a constant percent growth rate. The equation can be written in the formf(x) = a(1 + r)xor f(x) = abxwhere b = 1 + r. Exponential Growth and Decay Word Problems & Functions - Algebra & Precalculus ...
Growth and DecayBut sometimes things can grow (or the opposite: decay) exponentially, at least for a while.So we have a generally useful formula:y(t) = a × ekt Where y(t) = value at time "t" a = value at the start k = rate of growth (when >0) or decay (when <0) t =...

Exponential Growth: y = a(1 +r)x Exponential Decay: y = a(1 -r)x Remember that the original exponential formula wasy = abx. You will notice that in these new growth and decay functions, thebvalue (growth factor) has been replaced either by (1 +r) or by (1 -r). ...
Learning Outcomes Graph exponential growth and decay functions. Solve problems involving radioactive decay, carbon dating, and half life.Exponential Growth and DecayIn real-world applications, we need to model the behavior of a function. In mathematical modeling, we choose a familiar general function...
