Which of the sets of ordered pairs below represents a function? {(1,2), (2,3), (-2,4), (1,5)} {(5,2), (4,3), (-2,4), (1,5)} {(5,
Leto [7]
Notice, the set is just an x,y pair
the set without an X-REPEAT is a function
lets's see the first set for example
thus is not a function
check the others
Answer:
the graph is 1/2, y intercept is -6, last one in -7
Step-by-step explanation:

or, 4n - 5 =t
This is the required formula
