Exponential Growth or Decay? Growth Decay Growth
Exponential Growth or Decay? We need to know what e is…. e is number discovered by Euler. e = 2.71828…. Like π it is irrational. So because e is greater than 1 this function would be an exponential growth.
Performing Mathematics with e Recall: Well, since e is just a number /base all of these rules apply for e
Graphing e e follows all the rules of exponential growth and decay. GrowthDecay f(x)= 2e x f(x)= 2e -x x
Growth Decay f(x)= 2e x f(x)= 2e -x x : none y : (0,2) D: (- ∞,∞) R: (0, ∞) Asy: y = 0 x : none y : (0,2) D: (- ∞,∞) R: (0, -∞) Asy: y = 0 x : none y : (0,2) D: (- ∞,∞) R: (0, ∞) Asy: y = 0 x : none y : (0,2) D: (- ∞,∞) R: (0, -∞) Asy: y = 0 x
