Look at this set of ordered pairs: (10, 7) (13, 9) (10, 17) (9, 3) Is this relation a function? Choices: (A)yes (B)no

Understand Function Definition: Step 1: Understand what a function is in terms of ordered pairs. A relation is a function if each input (first number in each pair) has exactly one output (second number in each pair). Check for Repeated Inputs: Step 2: Check the ordered pairs for repeated inputs with different outputs. The pairs given are: (10, 7) (13, 9) (10, 17) (9, 3) Here, the input 10 corresponds to two different outputs, 7 and 17. Identify Violation of Function: Step 3: Since the input 10 has more than one output, this violates the definition of a function. Therefore, the relation is not a function.

Q. Look at this set of ordered pairs:

\newline

\newline

(13, 9)

\newline

(10, 17)

\newline

(9, 3)

\newline

Is this relation a function?

\newline

Choices:

\newline

(A) yes

\newline

(B) no

Understand Function Definition: Step $1$ : Understand what a function is in terms of ordered pairs. A relation is a function if each input (first number in each pair) has exactly one output (second number in each pair).
Check for Repeated Inputs: Step $2$ : Check the ordered pairs for repeated inputs with different outputs. The pairs given are: $\newline$ $(10, 7)$ $\newline$ $(13, 9)$ $\newline$ $(10, 17)$ $\newline$ $(9, 3)$ $\newline$ Here, the input $10$ corresponds to two different outputs, $7$ and $17$ .
Identify Violation of Function: Step $3$ : Since the input $10$ has more than one output, this violates the definition of a function. Therefore, the relation is not a function.
