Growth and decay

Question

h(p)=2(1.25)^(p)

 Growth or Decay: ______ 

b) Growth or Decay Factor:______ 

c) Growth or Decay Rate:______ 

d) Initial Value: ______ 

Answer 1

Exponential Growth:

y = a(1 + r)x

Exponential Decay:

y = a(1 - r)x

a = initial value (the amount before measuring growth or decay)

r = growth or decay rate (most often represented as a percentage and expressed as a decimal)

x = number of time intervals that have passed

set up your equation

h(p) = y = 2(1+.25)^p

 Growth or Decay: ____Growth__ - because your 1+.025 is greater than 1. if it was less than 1, it would be decay 

b) Growth or Decay Factor:_1.25____ 

c) Growth or Decay Rate:___0.25___ 

d) Initial Value: ____2__
