Use the vertical line test to determine if the graphed relation is a function Yes. One output results in one input.
O No. At least one input results in two outputs.
Yes. One input results in one output.
No. At least one output results in two inputs.

The given graph is a function because

One input result in one output.

Step-by-step explanation:

Vertical line test is a test used for testing whether a graphed relation is a  function or not. In a vertical line test, multiple vertical lines can be drawn at any point of the function. If the vertical lines intersect the graph only at one point, it means the there is only one value of y for a value of x, therefore the given relation is a function. If the vertical lines interest the graph at 2 or more locations, the given relation is not a function.

no one knows lol

step-by-step explanation:

-2 is the right
