Look at this set of ordered pairs: (17, 15) (7, 12) (12, 14) Is this relation a function? Choices: (A)yes (B)no

Define function: Step 1: Define a function. A relation is a function if each input (x-value) has exactly one output (y-value). We need to check if any x-value in the set of ordered pairs repeats with a different y-value. List x-values: Step 2: List the x-values from the ordered pairs. From the pairs (17, 15), (7, 12), and (12, 14), the x-values are 17, 7, and 12. Check for repeats: Step 3: Check for repeated x-values. The x-values 17, 7, and 12 are all different. There are no repeats, so each x-value is paired with exactly one y-value.

Q. Look at this set of ordered pairs:

\newline

(17, 15)

\newline

(7, 12)

\newline

(12, 14)

\newline

Is this relation a function?

\newline

Choices:

\newline

(A) yes

\newline

(B) no

Define function: Step $1$ : Define a function. $\newline$ A relation is a function if each input ( $x$ -value) has exactly one output ( $y$ -value). We need to check if any $x$ -value in the set of ordered pairs repeats with a different $y$ -value.
List $x$ -values: Step $2$ : List the $x$ -values from the ordered pairs. $\newline$ From the pairs $(17, 15)$ , $(7, 12)$ , and $(12, 14)$ , the $x$ -values are $17$ , $7$ , and $12$ .
Check for repeats: Step $3$ : Check for repeated $x$ -values. $\newline$ The $x$ -values $17$ , $7$ , and $12$ are all different. There are no repeats, so each $x$ -value is paired with exactly one $y$ -value.
