HELPPPPPPPPPPPPPPPPPPPP! ALGEBRA 1!
tHE ordered pairs in the sets shown below are of the form (x, y). In which set is y a function of x? {(0, 3), (1, 4), (2, 4), (2, 8)} {(1, 3), (2, 6), (3, 1), (6, 3)} {(1, 3), (3, 1), (3, 4), (4, 3)} {(1, -2), (1, 0), (1, 5), (1, 7)}
You can eliminate any sets where x is constant and y changes e.g sets 1,3 and 4 The reason is that set 1 has the values (2,4) and (2,8), set 3 has (3,1) and (3,4) and finally set 4 has all values of x as 1 but the y value continues to change. So the answer is set 2
