does {(0, 20), (2, 70), (10, 45), (1, 30), (3, 70)} show a function?(1 point)

Yes, the given set {(0, 20), (2, 70), (10, 45), (1, 30), (3, 70)} shows a function. In a function, each input (x-value) is paired with exactly one output (y-value). In this set, there are no repeated x-values and each input has a unique output. Therefore, it is a function.

what about the table

x 1,2,3,4,5
y -8,-6,-1,-2,-4

Yes, the given table:

x 1, 2, 3, 4, 5
y -8, -6, -1, -2, -4
shows a function. In a function, each input (x-value) is paired with exactly one output (y-value). In this table, there are no repeated x-values and each input has a unique output. Therefore, it is a function.
