Consider the following graph of an exponential function modeling the geometric sequence 1, 3, 9, 27, ... Which of the following statements are valid based on the graph? ( represents the growth factor of the function.) Select all correct answer choices.


When the coordinates (0, 1) and (-1, 1/3) are considered, r = 1/(1/3), which simplifies to 3.

When the coordinates (1, 3) and (2, 9) are considered, r = 3/9, which simplifies to 1/3.

When the coordinates (3, 27) and (2, 9) are considered, r = 27/9, which simplifies to 3.

When the coordinates (0, 1) and (-1, 1/3) are considered, r = (1/3)/1, which simplifies to 1/3.

When the coordinates (3, 27) and (2, 9) are considered, r = 9/27, which simplifies to 1/3.

When the coordinates (1, 3) and (2, 9) are considered, r = 9/3, which simplifies to 3.
