To determine if y is a function of x for each set of ordered pairs, we need to check if each x-value is associated with exactly one y-value.

Let's analyze each set:

A. {(-6,-7), (0,0), (0,4)}

For x=−6, y=−7.

For x=0, y=0 and y=4.

x=0 is associated with two different y-values (0 and 4).

Therefore, y is not a function of x in this set.

B: {(1,2), (2,1), (4,1)}

For x=1, y=2.

For x=2, y=1.

For x=4, y=1.

Each x-value is associated with exactly one y-value.

Therefore, y is a function of ...
