2 Growing a a Consan Percen Rae Example 2 During he 2000 s, he populaion of Mexico increased a a consan annual percen rae of 1.2%. (no amoun Since he populaion grew by he same percen each year, i can be modeled by an exponenial funcion. Ex: Calculae he populaion of Mexico for he years afer In 2000, he populaion was 100 million. Funcions Modeling Change: A Preparaion for Calculus, 4h Ediion, 2011, Connally
3 The populaion grew by 1.2%, so Pop. in 2001 = Pop. in % of Pop. in 2000 Pop. in 2001 = (100 Pop. in 2001 = 100 ( facored 100 Pop. in 2001 = 100 (1.012 Pop. in 2001 = million STOP HERE
4 Year One (2001 Wihou he final muliplicaion ( ( (1.012
5 Year Two The populaion grew by 1.2% again, so Pop. in 2002 = Pop. in % of Pop. in 2001 = [ (100] [ (100] = [100 (1.012] [100 (1.012] simplify = [100 (1.012] { } facored [100 (1.012] = [100 (1.012(1.012] = 100 (

7 Funcions Modeling Change: A Preparaion for Calculus, 4h Ediion, 2011, Connally Growing a a Consan Percen Rae Example 2 coninued Populaion of Mexico The populaion of Mexico increased by slighly more each year han i did he year before, because each year he increase is 1.2% of a larger number. Year ΔP, % increase in populaion P, populaion (millions The projeced populaion of Mexico, assuming 1.2% annual growh P, populaion (millions year
8 Growh Facor vs. Percen Growh Rae The growh facor is equal o ( 1 + growh rae The Growh Facor of an Increasing Exponenial Funcion: In Example 2, he populaion grew by 1.2%, so, New Populaion = Old Populaion + 1.2% of Old Populaion = ( * Old Populaion = * Old Populaion We call he growh facor. Funcions Modeling Change: A Preparaion for Calculus, 4h Ediion, 2011, Connally
9 Example 3 Carbon-14 is used o esimae he age of organic compounds. Over ime, radioacive carbon-14 decays ino a sable form. The decay rae is 11.4% every 1000 years. For example, if we begin wih a 200- microgram (μg sample of carbon-14 hen
10 Growh Facors vs. Percen Growh Raes The growh facor is equal o ( 1 + growh rae The Growh Facor of a Decreasing Exponenial Funcion: In Ex 3, he carbon-14 changes by 11.4% every 1000 yrs. New Amoun = Old Amoun 11.4% of Old Amoun = (1.114 * Old Amoun = * Old Amoun Alhough represens a decay facor, we use he erm growh facor o describe boh increasing and decreasing quaniies. Funcions Modeling Change: A Preparaion for Calculus, 4h Ediion, 2011, Connally
11 Funcions Modeling Change: A Preparaion for Calculus, 4h Ediion, 2011, Connally A General Formula for he Family of Exponenial Funcions An exponenial funcion Q = f ( has he formula form f ( = a b, a 0, b > 0, where a is he iniial value of Q (a = 0 and b, he base, is he growh facor. The growh facor is given by b = 1 + r where r is he decimal represenaion of he percen rae of change. If here is exponenial growh, hen r > 0 and b > 1. If here is exponenial decay, hen r < 0 and 0 < b < 1.
12 Funcions Modeling Change: A Preparaion for Calculus, 4h Ediion, 2011, Connally Applying he General Formula for he Family of Exponenial Funcions Example 6 Using Example 2, find a formula for P, he populaion of Mexico (in millions, in year where = 0 represens he year Soluion In 2000, he populaion of Mexico was 100 million, and i was growing a a consan 1.2% annual rae. The growh facor is b = = 1.012, and a = 100, so P = 100( Because he growh facor may change evenually, his formula may no give accurae resuls for large values of.
