It is given in the question that "doubling time". Thus, it will be exponential growth.
Express the mathematical form for the exponential growth model.
Calculate the value of k.
Then,the associated exponential model is
Tell whether each function represents exponential growth, exponential decay, or neither. Justify your responses.
Determine whether the function represents exponential growth or exponential decay. Identify the percent rate of change. Then graph the function.
