The initial amount if the value of the function at x = 0.
Here that value is 2000 for the f(x) and 1000 for the g(x), so the f(x) has the higher initial value.
For the second part, by looking at the graph, you can determine that the function for the g(x) is 1000(3)^x (because the g(1) is 3000). Plugging in two for both the function, you get the f(x) = 8,000 and the g(x) = 9,000, so the g(x) has the greater amount of bacteria after two days.
