Question

each of the following sets of ordered pairs represents a function except: (8, 7), (2, 11), (-3, -3), (8, -7) (5, 6), (7, 8), (9, 10), (11, 12) (-6, 12), (7, 3), (10, -9), (14, 5) (-15, 4), (-4, -8), (3, 4), (17, 22)

Explanation:

Step1: Recall function definition

A function is a relation where each input (x-value) has exactly one output (y-value).

Step2: Check x-values in each set

• First set: x=8 appears twice, paired with y=7 and y=-7.
• Second set: All x-values (5,7,9,11) are unique.
• Third set: All x-values (-6,7,10,14) are unique.
• Fourth set: All x-values (-15,-4,3,17) are unique.

Answer:

(8, 7), (2, 11), (-3, -3), (8, -7)
