Is the following relation a function? {(-2, 0), (3, 4), (7, 0), (9, 2)}  Is the following relation a function or not? Domain Range 4 7 -3 0 4 7 0 8 3  Find the domain and range of the relation below. Determine whether it is a function or not. ANSWER: Domain: (-∞, ∞) Range: (-∞, ∞) Yes, it is a function Is this relation a function or just 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)}  This is the value of f(3) when f(x) = -2 x – 4.                    What is the domain and range of this function. ANSWER: D: All Real Numbers R: [-5, ∞)  ANSWER: D: (-7, 9] R: (-5, 6] Daily Double The domain of a relation is positive even integers less than 6. The range is 2 more than half of x. Write the relation as a table of values. X Y ANSWER: X Y 0 2 2 3 4 4 What is the domain and range of this function. ANSWER: D = [-5, 5] R = [-5, 6] The domain of a relation is odd integers from -4 to 4. The range is 5 more than the domain. Write the relation as a table of values. ANSWER: x y -3 2 -1 4 1 6 3 8
