an example would be if you had line AB who's points are (5,3) and another at (1,5). Connecting diagonally. If you were to put a vertical line anywhere between the points. it only goes through one point. Making it a function.

A vertical line can be used to test whether or not a graph is a function.

f(x) = x2 This is a function by the vertical line test because a vertical line drawn through this function will only intersect the function at one point

True

Horizonatal line test is a test use to determine if a function is one-to-one. If a horizontal line intersects a function's graph more than once, then the function is not one-to-one. A one-to-one function is a function where every element of the range correspons to exactly one element of the domain. Vertical line test is a test used to determine if a function is a function or relation. If you can put a vertical line through graph and it only hits the graph once, then it is a function. If it hits more than once, then it is a relation.

"y = f(x) is a function if it passes the vertical line test. It is a 1-1 function if it passes both the vertical line test and the horizontal line test. " - In order to be a one-to-one function, it first has to BE a function and pass the vertical line test. For example, a relation on a graph like a circle that does not pass the vertical line test is not function nor one-to-one.

A vertical test line is useful because, by definition, a function has one and only one result value for each input value. If you can find a vertical line that intersects the curve of the line, then it is not a function. A simple example is a circle.

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.

To test if a storage tank is a function you can use the vertical line test (i.e. if a vertical line can be drawn through the storage tank where it intersects more than one point it is NOT a function). For example: function= vuvu non-function= void (A vertical line intersects two parts of the 'd' and 'o'.)

Not quite. You can use a vertical line test on the graph of the inverse mapping, OR you can use a horizontal line test on the original graph. The horizontal line test is used in the same way.

No. Because a vertical line will pass through two points on the graph.

Test it by the vertical line test. That is, if a vertical line passes through the two points of the graph, this graph is not the graph of a function.

no

A vertical line is drawn parallel to the Y-Axis. An example of an equation that is a vertical line is x = 3. In architecture, it is drawn perpendicular to the horizon line, regardless of the aspect ratio.
