A function h is defined for −4<x<6 with the following observed features:
• A vertical asymptote at x=−1.
• An open circle at (3,2) but no other breaks near x=3.
• No additional discontinuities on the interval.
On which of the following sets is h continuous?
a) (−4,3)∪(3,6)
b) (−4,−1)∪(−1,6)
c) (−4,−1)∪(−1,3)∪(3,6)
d) (−4,−1)∪(−1,3)
