Ineed on my exam. (15pts)

the population f(x), in millions, of state a of a country after x years is represented by the function shown below:

f(x) = 4(1.08)x

the graph shows the population g(x), in millions, of state b of the country after x years:

graph of exponential function g of x that curves up from left to right and goes through points 0 comma 2 and 9 comma 4

which conclusion is correct about the populations of state a and state b?

the original population of state a was double the original population of state b.
the original population of state b was double the original population of state a.
the original population of state a was four times the original population of state b.
the original population of state a was equal to the original population of state b.
