Which best describes the graph of the function f of x is equal to 4 times 1 point 5 to the x th power ?

For f(x) = 4(1.5)^x, substituting x = 0 gives f(0) = 4(1.5)^0 = 4, so the graph passes through (0, 4). Each time x increases by 1, the output is multiplied by the base 1.5. Therefore, the graph passes through (0, 4) and increases by a factor of 1.5, as choice C states.
