Afunction has a constant halving time. what type of function does this represent? a. decreasing linear b. exponential decay c. exponential growth d. increasing linear

The function which has a constant halving time is in the following form


Where:  A₀ is the initial amount
              h   is the half life time or the halving time.
              t    is the time
              A(t) the amount that remains at time t

The previous function represents an Exponential decay function.


so, The correct answer is option B. Exponential decay
