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

Define function as relation: A function is defined as a relation where each input (x-value) has exactly one output (y-value). To determine which set of ordered pairs does not represent a function, we need to check if there are any repeated x-values with different y-values in each set.Check first set: Check the first set {(-7,-4),(-4,8),(9,-7),(-3,2)} for any repeated x-values with different y-values. There are no repeated x-values in this set, so this set represents a function.Check second set: Check the second set {(-9,4),(5,-3),(3,-9),(-1,4)} for any repeated x-values with different y-values. There are no repeated x-values in this set, so this set represents a function.Check third set: Check the third set {(3,-4),(1,5),(3,-1),(-6,4)} for any repeated x-values with different y-values. The x-value 3 appears twice with different y-values (-4 and -1), so this set does not represent a function.Check fourth set: Check the fourth set {(9,-6),(-8,-6),(-7,-1),(2,4)} for any repeated x-values with different y-values. There are no repeated x-values in this set, so this set represents a function.

Q. Which set of ordered pairs does not represent a function?

\newline

\{(-7,-4),(-4,8),(9,-7),(-3,2)\}

\newline

\{(-9,4),(5,-3),(3,-9),(-1,4)\}

\newline

\{(3,-4),(1,5),(3,-1),(-6,4)\}

\newline

\{(9,-6),(-8,-6),(-7,-1),(2,4)\}

Define function as relation: A function is defined as a relation where each input ( extit{x}-value) has exactly one output ( extit{y}-value). To determine which set of ordered pairs does not represent a function, we need to check if there are any repeated extit{x}-values with different extit{y}-values in each set.
Check first set: Check the first set ${(-7,-4),(-4,8),(9,-7),(-3,2)}$ for any repeated $x$ -values with different $y$ -values. $\newline$ There are no repeated $x$ -values in this set, so this set represents a function.
Check second set: Check the second set ${(-9,4),(5,-3),(3,-9),(-1,4)}$ for any repeated $x$ -values with different $y$ -values. $\newline$ There are no repeated $x$ -values in this set, so this set represents a function.
Check third set: Check the third set $\{(3,-4),(1,5),(3,-1),(-6,4)\}$ for any repeated $x$ -values with different $y$ -values. $\newline$ The $x$ -value $3$ appears twice with different $y$ -values ( $-4$ and $-1$ ), so this set does not represent a function.
Check fourth set: Check the fourth set ${(9,-6),(-8,-6),(-7,-1),(2,4)}$ for any repeated $x$ -values with different $y$ -values. $\newline$ There are no repeated $x$ -values in this set, so this set represents a function.
