Note that k 0 since because the population is decreasing negative negative dt dP. Determine whether the expression below has exponential decay and if so find its initial value and decay rate. Decay exponentially at least for a while.
Exponential Growth and Decay Exponential decay refers to an amount of substance decreasing exponentially.
P 0 initial amount at time t 0. Scroll down the page for more examples and solutions for exponential growth and decay problems. The following diagram shows the formulas for exponential growth and decay problems. Lets do another one like this.
