Look at this set of ordered pairs: (9, 9) (9, 11) (7, 16) (10, 2) Is this relation a function? Choices: (A)yes (B)no

Understand Function Definition: Step 1: Understand the definition of a function. A relation is a function if each input (x-value) has exactly one output (y-value). Check if any x-value is repeated with different y-values. List X and Y Values: Step 2: List all x-values and their corresponding y-values from the given ordered pairs. (9, 9), (9, 11), (7, 16), (10, 2) Here, the x-value 9 is paired with y-values 9 and 11. Check Repeated Values: Step 3: Check for repeated x-values with different y-values. Since 9 is paired with both 9 and 11, this shows that the x-value 9 has more than one output.

\newline

(10, 2)

\newline

Is this relation a function?

\newline

Choices:

\newline

(A) yes

\newline

(B) no

Understand Function Definition: Step $1$ : Understand the definition of a function. A relation is a function if each input ( $x$ -value) has exactly one output ( $y$ -value). Check if any $x$ -value is repeated with different $y$ -values.
List X and Y Values: Step $2$ : List all $x$ -values and their corresponding $y$ -values from the given ordered pairs. $(9, 9)$ , $(9, 11)$ , $(7, 16)$ , $(10, 2)$ Here, the $x$ -value $9$ is paired with $y$ -values $9$ and $y$ $0$ .
Check Repeated Values: Step $3$ : Check for repeated $x$ -values with different $y$ -values. $\newline$ Since $9$ is paired with both $9$ and $11$ , this shows that the $x$ -value $9$ has more than one output.
