(a) Consider the exponential function f(t)=100(1.09t)f(t)=100(1.09t) which represents the amount of some quantity at time tt. Fill in the answers to the following questions.

(i) This function is undergoing exponential growth or decay.

ii) The initial amount of the quantity(at t=0t=0 ) is ------ (enter a number only)

The PERCENT growth/decay rate is ------- (enter a positive number in percent format - NOT decimal format. Enter a NUMBER ONLY - do NOT enter the "%" symbol itself!)

(b) Consider the exponential function f(t)=227(0.86t)f(t)=227(0.86t) which represents the amount of some quantity at time tt. Fill in the answers to the following questions.

(i) This function is undergoing exponential growth or decay.

(ii) The initial amount of the quantity (at t=0t=0 ) is ------ (enter a number only)

The PERCENT growth/decay rate is -------.
