    Answer: Hello mate!

    A constant tripling time means that there is a time T, a quantity triples when t = T, then triples again when t = 2T, and again when t = 3T.

    Then if A is the initual cuantity; we have a function of the form

    f(t) = A*3^(t/T)

    and you can see that:

    f(0) = A

    f(T) = A*3

    f(2T) = A*3^2 = (A*3)*3

    and so on:

    This function describes an exponential growth (because f(t) increases exponentialy over time)

    Answer: This represented a exponential growth function.

    Step-by-step explanation:

    Exponential growth is demonstrated when the rate of change of the value of any mathematical function[the change per unit of time] is proportional to the function’s present value, resulting in its value at any time being an exponential function of time or becomes a function in which the time value is the exponent.

    Given : A function has a constant tripling time. So it is highly increasing (exponentially) with the time i.e. the function is exponential function.
