Consider a function whose graph consists of a straight line segment joining the points (−3,1) and (2,4). The endpoint at (−3,1) is drawn with a filled (solid) dot, whereas the endpoint at (2,4) is drawn with a hollow (open) dot. Which of the following sets represents the domain of the function?
a) (−3,2]
b) [−3,2)
c) [−3,2]
d) (−3,2)
