Topic Notes
The growth/decay factor "(1+r)" dictates the rate of exponential growth and decay. We will work on questions related to growth/decay factor in this lesson.
exponential growth/decay: Af=Ai(f)periodtime
Af: final amount
Ai: initial amount
f : growth/decay factor
half-time→f=21
triple→f=3
ten-fold→f=10
increase by 10%→f=(1+10010)=1.1
decrease by 8%→f=(1−1008)=0.92
time : total time given
period : every length of time
