Which graph represents y=⌈x⌉over the domain 3≤x≤6 ? Number graph showing a range of zero to seven on the x and y axes. Three line segments are drawn on the graph. The first segment has a closed endpoint at (three, four) and an open end point at (four, four). The next segment has a closed endpoint at (four, five) and an open endpoint at (five, five). The third segment has a closed endpoint at (five, six) and a closed endpoint at (six, six). Number graph showing a range of zero to seven on the x and y axes. Four line segments are drawn on the graph. The first segment has a closed endpoint at (two, three) and an open endpoint at (three, three). The next segment has a closed endpoint at (three, four) and an open end point at (four, four). The next segment has a closed endpoint at (four, five) and an open endpoint at (five, five). The last segment has a closed endpoint at (5, 6) and an open endpoint at (six, six). Number graph showing a range of zero to seven on the x and y axes. Two line segments are drawn on the graph. The first segment has an open endpoint at (three, four) and a closed end point at (four, four). The next segment has an open endpoint at (four, five) and a closed endpoint at (five, five). The next segment has an open endpoint at (five, six) and a closed endpoint at (six, six). The point (three, three) is also drawn on the graph Number graph showing a range of zero to seven on the x and y axes. Three line segments are drawn on the graph. The first segment has an open endpoint at (three, four) and a closed end point at (four, four). The next segment has an open endpoint at (four, five) and a closed endpoint at (five, five). The last segment has an open endpoint at (5, 6) and a closed endpoint at (six, six).
