Question

Choose the compound inequality and graph that represents the situation. all real numbers that are greater than –6 but less than 6

Answer 1

You are looking for the intersection of -6 < x and x < 6. The first set is (-6, infinity) and the second set is (-infinity, 6). The intersection is (-6, 6), so the graph would look like an open circle at -6 and at 6 and all the points in between those 2 points.
