Which best describes the graph of the function f(x) = 4(1.5)x?

The graph passes through the point (0, 4), and for each increase of 1 in the x-values, the y-values increase by 1.5.
The graph passes through the point (0, 4), and for each increase of 1 in the x-values, the y-values increase by a factor of 1.5.
The graph passes through the point (0, 1.5), and for each increase of 1 in the x-values, the y-values increase by 4.
The graph passes through the point (0, 1.5), and for each increase of 1 in the x-values, the y-values increase by a factor of 4.

The domain of both functions is all real numbers.
The domain of f(x) is x > 5.
The domain of g(x) is x > 5.
The range of f(x) is y > 0.
The range of g(x) is y > 0.
