Select all of the following true statements if R = real numbers, I = integers, and W = {0, 1, 2, ...}.

a) W⊂I
b) R⊂W
c) 0∈I
d) Ø⊂R
e) {0, 1, 2, ...}⊆W
f) -2∈W

(I think that a, b, e and f are correct, but I just wanted to make sure)

thank you in advance:)

precal · Answer

f is not correct because it staes -2 is an element of W 
you only have 0 and the positive numbers in that set
