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.

mrb

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.
