Another way is to use the problem-solving strategy look for a pattern with the data. Final amount remaining after the decay over a period of time. But keep in mind that we also need to know that the graph is in fact an exponential function.
R the decay rate.
We use the command ExpReg on a graphing utility to fit an exponential function to a set of data points. I could write another exponential function. F of x is going to be equal to 2 times 2x plus b or 5. P 0 initial amount at time t 0.
