Which of the following sets of ordered pairs is not a function? {(0, 2), (1, 4), (2, 5), (3, 6)}
{(-1, 2), (1, 3), (1, 5), (-3, 4)}
{(0, 2), (1, 2), (2, 2), (3, 2)}
{(-4,3), (-1, 1), (-2,5), (3, 7)}

The second set

Step-by-step explanation:

The second set is not a function because there is an input with more than one output.

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.
