The figure shows the graph of a function. 

Which of the following statements is correct?

• the function is positive and concave up

• the function is negative and concave up

• the function is positive and concave down

• the function is negative and concave down

Choose all intervals where the graph is INCREASING (Choose all that apply)

• (-∞ , 1)

• (1 , 3)

• (3 , ∞)

What are the increasing and decreasing intervals of the graph?

• Increasing = (-∞,-3), (-1,2), (4, ∞)

  Decreasing = (-3,-1), (2,4)

• Increasing = (-3,-1), (2,4)

  Decreasing = (-∞,-3), (-1,2), (4, ∞)

• Increasing = (-∞,-3), (-1,2),

  Decreasing (-3,-1), (2,4), (4, ∞)

• Increasing = (-∞, 2), (-3, 1), (-1, ∞)

  Decreasing (2, -3), (1, -1)

Choose ALL intervals where the graph is DECREASING (Choose all that apply)

• (-∞ , 1)

• (1 , 3)

• (3 , ∞)

What is the range of the graph?

• (-∞,∞)

• [0,∞)

• (0,5)

• [-1,∞)

On what interval of x-values is this function decreasing?

• [2,∞)

• (-∞,2)

• The entire function is decreasing.

• The entire function is increasing.

What are the increasing intervals?

• (- ∞, 0) & (2, ∞ )

• (-1, 0) & (2,4)

• (0,2) & (-3, -7)

• (-8, -3) & (-7, 8)
