Look at this set of ordered pairs: (17, 2) (20, 15) (16, 7) (8, 4) Is this relation a function? Choices: (A)yes (B)no

Understand the problem: Step 1: Understand the problem. We need to determine if the set of ordered pairs represents a function. A relation is a function if each input (first number in each pair) has exactly one output (second number in each pair). Check for unique inputs: Step 2: Check for unique inputs. List the first elements of each ordered pair: 17, 20, 16, 8 Check if any input repeats. Conclusion based on inputs: Step 3: Conclusion based on inputs. Since all inputs are unique, each input has only one corresponding output. Therefore, this relation is a function.

Q. Look at this set of ordered pairs:

\newline

(17, 2)

\newline

(20, 15)

\newline

(16, 7)

\newline

(8, 4)

\newline

Is this relation a function?

\newline

Choices:

\newline

(A) yes

\newline

(B) no

Understand the problem: Step $1$ : Understand the problem. $\newline$ We need to determine if the set of ordered pairs represents a function. A relation is a function if each input (first number in each pair) has exactly one output (second number in each pair).
Check for unique inputs: Step $2$ : Check for unique inputs. $\newline$ List the first elements of each ordered pair: $\newline$ $17, 20, 16, 8$ $\newline$ Check if any input repeats.
Conclusion based on inputs: Step $3$ : Conclusion based on inputs. $\newline$ Since all inputs are unique, each input has only one corresponding output. Therefore, this relation is a function.
