1.) {(3, 7), (3, 6), (5, 4), (4, 7)} ➜ Is not a Function

2.) {(1, 5), (3, 5), (4, 6), (6, 4)} ➜ Is a Function

3.) {(2, 3), (4, 2), (4, 6), (5, 8)} ➜ Is not a Function

4.) {(0, 4), (3, 2), (4, 2), (6, 5)} ➜ Is a Function

Step-by-step explanation:

{(3, 7), (3, 6), (5, 4), (4, 7)} ➜  Is not a Function, since (3, 7), (3, 6) share same x.

{(1, 5), (3, 5), (4, 6), (6, 4)} ➜ Is a Function, since each relation doesn't share the same x.

{(2, 3), (4, 2), (4, 6), (5, 8)} ➜ Is not a Function, since (4, 2), (4, 6) share same x.

{(0, 4), (3, 2), (4, 2), (6, 5)} ➜ Is a Function, since each relation doesn't share the same x.

452,489 to the nearest thousand is 452,000

50*10 is greater

step-by-step explanation:
