Determine if the following is a function, and if it is a one-to-one function. {(5,1),(4,7),(3,3),(1,8),(5,9)} Not a function A function, not one-to-one A one-to-one function

Identify x-values: Identify the x-values from the given set of ordered pairs. The ordered pairs are (5,1), (4,7), (3,3), (1,8), (5,9). The x-values are 5, 4, 3, 1, 5.Check for repetition: Check for repeated x-values. The x-values identified are 5, 4, 3, 1, 5. We can see that the value 5 is repeated.Determine function status: Determine if the relation is a function. A relation is a function if each x-value corresponds to exactly one y-value. Since the x-value 5 corresponds to two different y-values (1 and 9), the relation is not a function.

Q. Determine if the following is a function, and if it is a one-to-one function.

\newline

\{(5,1),(4,7),(3,3),(1,8),(5,9)\}

\newline

Not a function

\newline

A function, not one-to-one

\newline

A one-to-one function

Identify $x$ -values: Identify the $x$ -values from the given set of ordered pairs. The ordered pairs are $(5,1)$ , $(4,7)$ , $(3,3)$ , $(1,8)$ , $(5,9)$ . The $x$ -values are $5$ , $4$ , $x$ $0$ , $x$ $1$ , $5$ .
Check for repetition: Check for repeated $x$ -values. The $x$ -values identified are $5$ , $4$ , $3$ , $1$ , $5$ . We can see that the value $5$ is repeated.
Determine function status: Determine if the relation is a function. A relation is a function if each $x$ -value corresponds to exactly one $y$ -value. Since the $x$ -value $5$ corresponds to two different $y$ -values ( $1$ and $9$ ), the relation is not a function.
