Look at this set of ordered pairs: (16, 17) (17, 2) (12, 11) (12, 15) 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). Examine Ordered Pairs: Step 2: Examine the given ordered pairs for repeated x-values: (16, 17), (17, 2), (12, 11), (12, 15). Here, the x-value 12 appears twice with different y-values (11 and 15). Determine Relation Type: Step 3: Determine if the relation is a function. Since the x-value 12 maps to two different y-values, this violates the definition of a function.

(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).
Examine Ordered Pairs: Step $2$ : Examine the given ordered pairs for repeated $x$ -values: $(16, 17)$ , $(17, 2)$ , $(12, 11)$ , $(12, 15)$ . Here, the $x$ -value $12$ appears twice with different $y$ -values ( $11$ and $15$ ).
Determine Relation Type: Step $3$ : Determine if the relation is a function. Since the $x$ -value $12$ maps to two different $y$ -values, this violates the definition of a function.
