Problem
A function is defined by the following three connected pieces:
(i) A horizontal ray on y=1 starting at (−4,1) (solid) and extending indefinitely to the left.
(ii) A straight line segment from (−4,1) (solid) to (2,−5), but open at (2,−5).
(iii) A horizontal ray on y=−5 starting at (2,−5) (solid) and extending indefinitely to the right.
Determine the range of the function.
(a) (−5,1]
(b) {−5,1}
(c) [−5,1]
(d) [−5,1)
