Which of the sets of ordered pairs represents a function? a = {(1, −2), (3, −5), (5, 2), (7, 5)} b = {(4, 2), (4, −2), (9, 3), (9, −3)} only a only b both a and b neither a nor b

A function is a relation for which each value from the set the first components of the ordered pairs is associated with exactly one value from the set of second components of the ordered pair.

A = {(1, -2); (3, -5), (5, 2), (7, 5)} - it's a function

B = {(4, 2), (4, -2), (9, 3), (9, -3)} - it's not a function

answer:   (s+1)(s+4)

step-by-step explanation:

factor s2+5s+4

s2+5s+4

=(s+1)(s+4)

the answer is -6

step-by-step explanation:

the answer is -6 because its next to the variable m
