very important math problem

Question

N is the set of integers that are greater than or equal to −3 and less than 1. Write the set in roster form.

N={ }

Answer 1

N is the set of integers that are greater than or equal to −3 and less than 1.

You might find it helpful to draw it on a number line.

The boundaries are -3 (inclusive) and +1 (exclusive).

"Roster form" is just a fancy way of saying write out the numbers! :-)

N = { -3, -2, -1, 0}

We include 0 because it is an integer, and we don't include 1 because the question says less than.
