Which set of ordered pairs does not represent a function? Answer (5,-1),(7,-9),(-8,-1),(8,-7) (4,3),(-6,2),(-3,5),(9,3) (-4,1),(2,-7),(8,-2),(-7,-3) (-1,7),(7,1),(5,-7),(7,-8)

To determine which set of ordered pairs does not represent a function, we need to check if each input (x-value) is associated with exactly one output (y-value).<br /><br />Let's analyze each set of ordered pairs:<br /><br />1. $\{ (5,-1),(7,-9),(-8,-1),(8,-7)\} $<br /> - Each x-value is unique and associated with only one y-value.<br /> - This set represents a function.<br /><br />2. $\{ (4,3),(-6,2),(-3,5),(9,3)\} $<br /> - Each x-value is unique and associated with only one y-value.<br /> - This set represents a function.<br /><br />3. $\{ (-4,1),(2,-7),(8,-2),(-7,-3)\} $<br /> - Each x-value is unique and associated with only one y-value.<br /> - This set represents a function.<br /><br />4. $\{ (-1,7),(7,1),(5,-7),(7,-8)\} $<br /> - The x-value 7 is associated with two different y-values (1 and -8).<br /> - This set does not represent a function.<br /><br />Therefore, the set of ordered pairs that does not represent a function is $\{ (-1,7),(7,1),(5,-7),(7,-8)\} $.
