Look at this set of ordered pairs: (0, 1) (8, –15) (8, 1) (15, 15) Is this relation a function? Choices: (A)yes (B)no

Check x-values: Check x-values in the ordered pairs: (0, 1), (8, –15), (8, 1), (15, 15). x-values: 0, 8, 8, 15.Notice repeated x-value: Notice that the x-value 8 is repeated.Different outputs for same input: Since the x-value 8 repeats with different y-values (–15 and 1), this means two different outputs for the same input.Relation not a function: A function must have exactly one output for each input. Therefore, this relation is not a function.

Q. Look at this set of ordered pairs:

\newline

(0, 1)

\newline

(8, -15)

\newline

(8, 1)

\newline

(15, 15)

\newline

Is this relation a function?

\newline

Choices:

\newline

(A) yes

\newline

(B) no

Check $x$ -values: Check $x$ -values in the ordered pairs: $(0, 1)$ , $(8, –15)$ , $(8, 1)$ , $(15, 15)$ . $\newline$ $x$ -values: $0$ , $8$ , $8$ , $x$ $0$ .
Notice repeated x-value: Notice that the x-value $8$ is repeated.
Different outputs for same input: Since the $x$ -value $8$ repeats with different $y$ -values ( $–15$ and $1$ ), this means two different outputs for the same input.
Relation not a function: A function must have exactly one output for each input. Therefore, this relation is not a function.
