Algebra-1

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. {(2,7), (7,2)}:

x=2 maps to y=7.

x=7 maps to y=2.

Each x value (2 and 7) is associated with a unique y value (7 and 2, respectively).

This set represents a function.

B. {(1,3), (6,4)}:

x=1 maps to y=3.

x=6 maps to y=4.

Each x value (1 and 6) is associated with a unique y value (3 and 4, respectively).

This set represents a function.
