Question

How do you write the set in roster form? In set builder notation?

D is the set of whole numbers less than 3.

A. D = {0,1,2,3,4,5}; D = {x is a whole number, x < 3}

B. D = {0,1}; D = {x | x < 3}

C. D = {0,1,2}; D = {x | x is a whole number, x < 3}

D. D = {0,1,2,3,4,5,6,7}; D = {x < 3}

Answer 3

Look at the roster form in B. It's missing something. Also, the set builder form in B isn't restrictive enough, since it doesn't limit x to whole numbers (so it includes, for example, 1.5, \(\sqrt{2}\), and -12).
