Question

look at this graph: is this relation a function? yes no

Explanation:

Step1: Identify all x-values

List x-coordinates of points: $-4, -3, -2, -2, 0, 1$

Step2: Apply vertical line test

Check for repeated x-values: $x=-2$ appears twice, with different y-values ($1$ and $-1$). A function cannot have one x mapped to multiple y-values.

Answer:

yes is incorrect, no is correct. The final answer is no.
