What are all the subsets of the set?
{-8, 4}
a. 0 with a line through it, {-8}, {4}
b. {-8}, {4}, {-8, 4}
c. {-8}, {4}
d. 0 with a line through it, {-8}, {4}, {-8, 4}

Answer 1

It's A.

Answer 2

Sorry -- D
a subset can include all the elements

quick check:
a set of n elements has 2^n subsets
They are called the power set

the zero with a line is the Greek letter phi
