Asha found that a vertical line intersects the graph of at two points. What can Asha conclude about ? It is a function of x but not a relation. It is a relation but not a function of x. It is both a function of x and a relation. It is neither a function of x nor a relation.
The vertical line test is used to check if a line is a
function of a graph or not. The test states that if it crosses a graph at more
than 1 point, then it is not a function but simply just a relation of that
graph. So in this case, it is a relation
but not a function of x.
