Question

List all of the elements of set A if A = {xlx is an integer and -6 < x <0}

O {-6, -5, -4,-3, -2,-1, O}
O{-6, -5, -4,-3, -2, -1}
O {-5,-4, -3, -2,-1)

Answer 1

{-5,-4, -3, -2,-1}

Explanation:

-6 < x < 0 means all the things BETWEEN -6 and 0, NOT INCLUDING -6 and 0 because "<" DOESN'T HAVE an equal.

We want integers between -6 and 0. Recall that integers are:

...-3, -2, -1, 0, 1, 2, 3, ....

So what are all the integers BETWEEN -6 and 0? They are:

-5, -4, -3, -2, and -1

Last answer choice is right.
