Penerapan fungsi Eksponensial dalam Ekonomi
Contoh
a). Tahunan F = P(1 + i)n = 1000 ( 1 + 10%)3 = 1000 ( 1 + 0,1)3 = 1000 (1,1)3 = 1000 (1,331) = 1331 b). Semesteran F = P(1 + i/m)n.m = 1000 { 1 + (10% / 2) }3.2 = 1000 { 1 + (0,1 / 2)}6 = 1000 { 1 + (0,05)}6 = 1000 (1,05)6 = 1000 (1,3400956) = 1340
c). Bulanan F = P(1 + i/m)n.m = 1000 { 1 + (10% /12) }3.12 = 1000 { 1 + (0,1 / 12)}36 = 1000 { 1 + (0,00833)}36 = 1000 (1,00833)6 = 1000 (1,346578322) = 1346,578322
Fungsi Pertumbuhan
Contoh
y = 200 {1 ─ e-0,1(x)} = 200 {1 ─ e-0,1(10)} = 200 {1 ─ e-1} = 200 {1 ─ 10-1} = 200 {1 ─ 1/10} = 200 {1 ─ 0,1} = 200 {0,9} = 180
