Yes, you can consider it a relation between the points on the x-axis, and the points on the y-axis. In fact, ANY subset of R squared (in other words, any subset of the points on a plane), including the empty set, sets that contain single points, and larger sets, can be considered a relation in R squared (i.e., two sets of real numbers).
What else can I help you with?
Is a vertical line a relation?
Yes it is, but it is not a function.
What is the only type of line that is not a function?
A vertical line. Remember that one test to see if a relation is a function is the vertical line test. A vertical line would fail that of course.
The graph of a relation must pass the vertical line test?
True
Which of the following would offer proof that a relation is a function?
a vertical line
If no vertical line intersects the graph of a relation in more than one point then the relation is a function?
True.
What does a straight line up and down mean in math?
Vertical
What is a vertical symmetry in math?
a line that goes up and down
Can relations pass the vertical line test?
Yes, relations can pass the vertical line test if they are functions. The vertical line test states that if a vertical line intersects a graph at more than one point, the relation represented by the graph is not a function. Therefore, for a relation to pass the vertical line test, each input (or x-value) must correspond to exactly one output (or y-value). If it meets this criterion, it can be classified as a function.
The graph of a relation must pass the vertical line test true or false?
False
How does you know that relation is a function?
One way is to try the vertical line test on a graph!
What test tells if a relation is a function?
To determine if a relation is a function, you can use the "vertical line test." If any vertical line drawn on the graph of the relation intersects the graph at more than one point, then the relation is not a function. Additionally, in a set of ordered pairs, a relation is a function if each input (or x-value) corresponds to exactly one output (or y-value).
What is the math symbol for incongruency?
Three vertical lines, |, with a diagonal line across them.
