Here's the question you clicked on:
x1xofxaxkndx
is this a function?

For a relation to be a function, each x value can be mapped to only a single y value. In a vertical line, the x-coordinate of every point is the same, so a single x-value is mapped to every real number. That is more than a single y-value, so it is not a function.
then it would be nobecause its only going down the x
An easy way to tell if a relation is a function from a graph is the vertical line test. Think of a vertical line moving from left to right on the graph. If in any position, the vertical line intersects more than one point of the relation, then the relation is not a function.
It is not a function.
All lines are functions except vertical lines.
thank you i got it now lol
