A function’s graph comprises two disjoint pieces:
1. A horizontal ray on the line y=2 that begins at (−6,2) (solid) and extends indefinitely to the left.
2. A closed semicircle of radius 2 centred at (2,0) that lies entirely below the x-axis.
What is the range of the function?
(a) [−2,2]
(b) [−2,0]
(c) [−2,0]∪{2}
(d) (−2,0]∪{2}
