Look at this set of ordered pairs: (1, 15) (16, 2) (15, 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). We need to check if any x-value in the given ordered pairs repeats with different y-values. List x-y values: List all the x-values and their corresponding y-values from the ordered pairs. (1, 15), (16, 2), (15, 7) Here, the x-values are 1, 16, and 15. Check for repeats: Check for repeated x-values. The x-values 1, 16, and 15 are all different; none of them repeat. Conclude function: Conclude if the relation is a function. Since no x-value is repeated with a different y-value, this relation is a function.

Q. Look at this set of ordered pairs:

\newline

(1, 15)

\newline

(16, 2)

\newline

(15, 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). We need to check if any $x$ -value in the given ordered pairs repeats with different $y$ -values.
List $x-y$ values: List all the $x$ -values and their corresponding $y$ -values from the ordered pairs. $\newline$ $(1, 15), (16, 2), (15, 7)$ $\newline$ Here, the $x$ -values are $1$ , $16$ , and $15$ .
Check for repeats: Check for repeated $x$ -values. $\newline$ The $x$ -values $1$ , $16$ , and $15$ are all different; none of them repeat.
Conclude function: Conclude if the relation is a function. $\newline$ Since no $x$ -value is repeated with a different $y$ -value, this relation is a function.
