how do you find the decay rate of an exponential function . Where y t value at time t. So after each period the value is only 95 of the period before.

We use the command ExpReg on a graphing utility to fit an exponential function to a set of data points. Y a 1 -bx. T time number of periods.
X0 is the initial value at time t0.
Decay exponentially at least for a while. So this is an exponential. Where N new situation after t periods. Let us look into some example problems to understand the above concept.

We can also use the POWER function in place of the Exponential function in Excel but the only difference is the measurement precision.

Exponential regression is used to model situations in which growth begins slowly and then accelerates rapidly without bound or where decay begins rapidly and then slows down to get closer and closer to zero.

DNdt prop -Nt That is the rate at which a population of something decays is directly proportional to the negative of the current population at time t.

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.
