Exponential Functions Growth and Decay Graph

Is this exponential growth or decay?

• Growth

• Decay

• The graph shows decay, then growth

• Neither

Look at the graph and answer each question. Does the graph show growth or decay? What is the y-intercept? What is the asymptote?

• Growth

  y-intercept: (0, 5)

  asymptote: y = 0

• Decay

  y-intercept: (0, 5)

  asymptote: y = 0

• Growth

  y-intercept: (0, 5)

  asymptote: y = 5

• Decay

  y-intercept: (0, 5)

  asymptote: x = 0
