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

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'.)
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.
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.
In MATLAB, you can insert vertical or horizontal lines on a graph by using the xline or yline functions, respectively. For example, to add a vertical line at ( x = a ), use xline(a, 'r--'), and for a horizontal line at ( y = b ), use yline(b, 'g--'). These lines can help you visually test if a given relation defines a function by checking if any vertical line intersects the graph at more than one point (the vertical line test).
