Look at the graph and answer each question.

Is the graph increasing or decreasing?

What is the y-intercept?

What is the asymptote?

• Increasing

  y-intercept: (0, 5)

  asymptote: y = 0

• Decreasing

  y-intercept: (0, 5)

  asymptote: y = 0

• Increasing

  y-intercept: (0, 5)

  asymptote: y = 5

• Decreasing

  y-intercept: (5, 0)

  asymptote: x = 0
