Which statement is true about the graph of f(x) = (1/8)^x?

1) The graph is always increasing.
2) The graph is always decreasing.
3) The graph passes through (1,0).
4) The graph has an asymptote, x = 0.

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.
