To determine which set of ordered pairs does not represent y as a function of x, we need to check if each x value is associated with only one y value.

Let's analyze each set:

A. {(-6,30), (0,20), (3,15)}:

x=−6 maps to y=30.

x=0 maps to y=20.

x=3 maps to y=15.

Each x value ( -6, 0, and 3) is associated with a unique y value ( 30, 20, and 15, respectively). This set represents a function.

B. {(3,1), (3,2), (4,6)}:

x=3 maps to y=1.

x=3 also maps to y=2.

Here, x=3 is associated with two different y values (1 and 2).

This set does not represent a function because x=3 has...
