Answer:
Yes, the relation is a function.
Step-by-step explanation:
Using the vertical line test is quite simple, really. You draw imaginary lines vertically down the graph and if at any point the imaginary lines intersect the given graph more than once, it's not a function. That simple, honestly. So, I used an online graphing calculator to graph the points (-6,-2), (-2,6), (0,3), (3,5), and then drew my imaginary lines. they did not intersect more than once so this indicates the relation is a function.
I really hope this helps you:) let me know if you have any more questions about this.
P.S. The lines on the image are nowhere near to straight so I'm sorry about that. freehanding with a mouse is a bit difficult.
