Look at this set of ordered pairs: (3, 1) (18, 6) (18, 7) Is this relation a function? Choices: (A)yes (B)no

Define Function: 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 in the set of ordered pairs is repeated with different y-values. Examine Ordered Pairs: Examine the ordered pairs. The ordered pairs given are (3, 1), (18, 6), and (18, 7). Here, the x-value 18 is associated with two different y-values, 6 and 7. Determine Functionality: Determine if the relation is a function. Since the x-value 18 maps to more than one y-value, this violates the definition of a function. Therefore, the relation is not a function.

Q. Look at this set of ordered pairs:

\newline

(3, 1)

\newline

(18, 6)

\newline

(18, 7)

\newline

Is this relation a function?

\newline

Choices:

\newline

(A) yes

\newline

(B) no

Define Function: Understand the definition of a function. $\newline$ A relation is a function if each input ( $x$ -value) has exactly one output ( $y$ -value). Check if any $x$ -value in the set of ordered pairs is repeated with different $y$ -values.
Examine Ordered Pairs: Examine the ordered pairs. $\newline$ The ordered pairs given are $(3, 1)$ , $(18, 6)$ , and $(18, 7)$ . Here, the $x$ -value $18$ is associated with two different $y$ -values, $6$ and $7$ .
Determine Functionality: Determine if the relation is a function. $\newline$ Since the $x$ -value $18$ maps to more than one $y$ -value, this violates the definition of a function. Therefore, the relation is not a function.
