Answer:
a) End behavior: As → ∞, () → . As → −∞, () → .
Looking at the ends of the graph, as goes to ∞ or −∞, gets
closer to .
b) End behavior: As → ∞, () → . As → −∞, () → .
Looking at the ends of the graph, as x goes to ∞ or −∞, gets
closer to .
c) End behavior: As → ∞, () → ∞, and as → −∞, () → −∞.
Looking at the ends of the graph, as goes to ∞, continues to increase
toward ∞, and as x goes to −∞, continues to decrease toward −∞.
