A function is represented solely by a straight line segment joining the points (−3,2)(-3,2) and (5,−4)(5,-4). The endpoint at (−3,2)(-3,2) is solid, while the endpoint at (5,−4)(5,-4) is hollow. Which of the following is the domain of the function? (a) [−3,5][-3,5] (b) [−4,2][-4,2] (c) [−3,5)[-3,5) (d) (−3,5](-3,5]
