The base of the function
For the following exercises, determine whether the equation represents exponential growth, exponential decay, or neither. Explain.
Tell whether the function represents exponential growth or exponential decay. Then graph the function.
There was a sample of
milligrams of a radioactive substance to start a study. Since then, the sample has decayed by
be the number of years since the start of the study. Let
be the mass of the sample in milligrams.
