Suppose a grain of dust is in the shape of a sphere with a radius 2 × 10−7

m. What is
the volume of the dust grain? Use the
volume formula V = 4
3
πr 3 with 3.14 as an
approximation for π. Write your answer in
scientific notation rounded to two decimal
places.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
