Considering these functions: f(x) = 3x^3 + 2
g(x) = 3√x-2 / 3

Which statements, if any, are true about these functions?
I. The function f(g(x)) = x for all real x
II. The function g(f(x)) = x for all real x
III. Functions f and g are inverse functions

The table below shows the approximate masses of a dust particle and a grain of pollen. dust particle 0.000000778 g grain of pollen 0.00000000155 g the mass of a dust particle can be estimated and written in the form a × 10^b, where a = 8 and b = the mass of a grain of pollen can be estimated and written in the form a × 10^b, where a = 2 and b = based on the estimates, the mass of a dust particle is approximately blank times larger than the mass of a grain of pollen.
