Math Algebra 1 Exponential growth decay Exponential growth decay. The exponential decay function is y gt abt where a 1000 because the initial population is 1000 frogs The annual decay rate is 5 per year stated in the problem. It will calculate any one of the values from the other three in the exponential decay model equation.
But it obviously obeys lim t e t log t e 05 t 0.
So we have a generally useful formula. They also adhere to the characteristic feature of the graphs of all functions. A value at the start. But it obviously obeys lim t e t log t e 05 t 0.
