Vertical Line Math Example

Explaining why a vertical line doesn t represent a function.

Vertical line math example.

If we say that the motion is vertical it means the direction of movement is top down or bottom up. Vertical lines in math. All points on the line will have the same x coordinate. States that if a vertical line intersects the graph of the relation more than once then the relation is a not a function.

You will see a correct vertical line test and an incorrect vertical line test. The equation of a vertical line always takes the form x k where k is any number and k is also the x intercept. In math the y axis is. Vertical line test is generally done by using a ruler.

A vertical line is one the goes straight up and down parallel to the y axis of the coordinate plane. Using vertical line test the graph given represents a function as the vertical line drawn intersects the graph at only one point. The vertical lines have no slope. If we think of a vertical line as an infinite set of x values then intersecting the graph of a relation at exactly one point by a vertical line implies that a single x value is only paired to a unique value of y.

Are the points of vertical lines. Examples of vertical line test. Next we show you a few examples where the vertical line test was used to determine if the graph is a function. Some examples showing how to use the vertical line test to check if a relation is a function or not.

Vertical lines help determine if a relation is a function in math. For example 2 0 3 0 4 0 etc. A vertical line is drawn across the edge of the ruler from one end of the x axis to the other end. Some examples are shown below.

Sheffer stroke in logic verti bar vbar stick vertical line vertical slash bar pike or pipe and several variants on these names it is occasionally considered an allograph of broken bar see below. Is a way to determine if a relation is a function. In the figure above drag either point and note that the line is vertical when they both have the same x coordinate. That is every x value of a function must be paired to a single y value.

The line has to be vertical as illustrated above. The vertical bar is a glyph with various uses in mathematics computing and typography it has many names often related to particular meanings. If you think about it the vertical line test is simply a restatement of the definition of a function. Similarly the line which goes from left to right and is parallel to the x axis is called a horizontal line.

Movement can also be vertical. The vertical line test. The vertical line test supports the definition of a function. More about vertical line test.
