A small nest of wasps has an exponential growth rate of 13% per month. If the nest currently has 5,000 wasps, the situation can be modeled by the equation w (t) = 5,000(1.13)^t, where w is the number of wasps after time t month. Which of the following statements is true about the equation?
A. As t increases, w decreases quickly at first and then slowly.
B. As t increases, w increases quickly at first and then slowly.
C. As t increases, w increases slowly at first the quickly.
D. As t increases, w decreases slowly at first the quickly.
