Exponential Functions Characteristics and Exponential Growth and Decay

• Growth

• Decay

Identify the following exponential functions characteristics, then graph the function:

• H.A: y = 4

  y-intercept: (0, 4.03)

  Behavior: as x approaches +infinity then the function exponentially grows, as x approaches -infinity then the function approaches the H.A. where y = 4

• H.A: y = 4

  y-intercept: (0, -4.03)

  Behavior: as x approaches +infinity then the function exponentially grows, as x approaches -infinity then the function approaches the H.A. where y = 4

• H.A: y = -4

  y-intercept: (0, 4.03)

  Behavior: as x approaches +infinity then the function exponentially grows, as x approaches -infinity then the function approaches the H.A. where y = -4

• H.A: y = 4

  y-intercept: (0, 4.03)

  Behavior: as x approaches +infinity then the function approaches the H.A. where y = 4, as x approaches -infinity then the function exponentially increases
