If an initial population of size P has a half-life of d years or any other unit of time then the formula to find the final number A in t years is given by A P 12td. So now that we have computed the decay factor we get that the exponential decay formula is. And Quadratic equations functions and graphs.
Where y t value at time t.
Heres an exponential decay function. Differential Equations Representing Growth and Decay. This is an exponential decay problem. Where y t value at time t.
