ANSWER: Domain: (-∞, ∞) Range: (-∞, ∞) Yes, it is a function

Is this relation a function or just a relation?

ANSWER: A relation

Use the Domain and Range of the following relations to determine which is a function. a. b. c. d. {(-6, -2), (-8, 8), (-6, -9)} {(-6, -2), (-8, -8), (-5, -9)} {-6, -8, -6, -9} {(-6, -2), (-8, -8), (-8, 5), (-5, -9)}
