Kwame is given the graph.
On a coordinate plane, the x-axis ranges from negative 2 to 6 in increments of 1. The y-axis is labeled from 1 to 9 in increments of 1. A smooth increasing curve passes through the points (0, 1), (1, 2), (2, 4), and (3, 8).
Which of the following best describes the graph?
an exponential function with a growth factor of 2
a quadratic equation with differences of 1, then 2, then 4, ...
a quadratic function with a constant difference of 2
an exponential function with growth factors of 1, then 2, then 4, ...
