Given the function defined in the table below, find the average rate of change, in simplest form, of the function over the interval 2≤x≤4. chart:
x : 2, 4, 6, 8
f(x):56, 32, 16.8

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.
