• Properties of exponential functions a>1 For example, let's look at Properties of the exponential growth function Domain: Range: Root(s): y-intercept: Increasing of Decreasing: Concavity: Asymptote(s):
• Properties of exponential functions As an example let's look at 0<a<1 Properties of the exponential decay function Domain: Range: Root(s): y-intercept: Increasing or Decreasing: Concavity: Asymptote(s):
• Properties of logarithmic functions For example, let's look at a > 0, a ≠ 1 Properties of the logarithmic growth function Domain: Range: Root(s): y-intercept: Increasing of Decreasing: Concavity: Asymptote(s):
• Properties of logarithmic functions 0<a<1 As an example we'll look at Properties of the logarithmic decay function Domain: Range: Root(s): y-intercept: Increasing of Decreasing: Concavity: Asymptote(s):
