\[
\{(11,17),(5,-8),(16,1),(5,-19),(-9,8)\}
\]
Yes
No
Solution
Solution Steps
Step 1: Understand the Definition of a Function
A relation is a function if each input (x-value) corresponds to exactly one output (y-value). In other words, no two ordered pairs in the relation can have the same x-value with different y-values.
Step 2: Analyze the Given Relation
The given relation is:
\[
\{(11,17),(5,-8),(16,1),(5,-19),(-9,8)\}
\]
We need to check if any x-value is repeated with different y-values.
Step 3: Identify Repeated x-Values
The x-value 5 appears twice: once with y = -8 and once with y = -19.
All other x-values (11, 16, -9) are unique.
Step 4: Determine if the Relation is a Function
Since the x-value 5 corresponds to two different y-values (-8 and -19), the relation is not a function.
