Question

why is your choice above a function?
the relation passes the vertical line test.
there is at least one vertical line that contains more than one ordered pair from the relation.
there is an input value (x) that corresponds with more than one output value (y).
there is at least one x - value that has more than one y - value paired with it.

Explanation:

A relation is defined as a function if every input (x-value) has exactly one corresponding output (y-value). A key visual check for this is the vertical line test: if any vertical line drawn through the graph intersects the relation more than once, it is not a function. Passing the vertical line test confirms that no x-value maps to multiple y-values, satisfying the definition of a function. The other options describe characteristics of non-functions.

Answer:

A. The relation passes the vertical line test.
