List all of the elements of set a if a = {x|x is an integer and -6 ≤ x < 0} a. {-6, -5, -4, -3, -2, -1, 0} b. {-6, -5, -4, -3, -2, -1} c. {-5, -4, -3, -2, -1}

This is an example of a set defined by describing the property of its elements: every element in the set must be an integer, greater than or equal to -6, and less than zero (ecluded).

So, all the numbers that satisfy this requests are -6,-5,-4,-3,-2,-1, and the answer is thus b.
