The Vertical Line Test for Functions:
If any vertical line intercepts a graph in more than one point, the graph does not define y as a function of x.
By the definition of a function, for each value of x we can have at most one value for y.

What is the definition for vertical line test in the subject math?

Can a one to one function not be a function?
"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.
How do you use a vertical line test to determine if a graph represents a function?
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.
What is the graph combination of line segments that passes the vertical line test?
Many to one function
Is a parabola a function?
Y = X2 ===== The graph of this parabola is crossed only at a point and once by a vertical line, so it is a function. Passes the vertical line test.
What does a vertical line test mean in math?
Absolute value |-5| = 5

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.
What does a vertical line tell you?
A vertical line can be used to test whether or not a graph is a function.
What is a vertical symmetry in math?
a line that goes up and down
What does a straight line up and down mean in math?
Vertical

Can you determine whether the inverse of a function is a function by using vertical line test?
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.
Does a circle pass the vertical line test?
No. Because a vertical line will pass through two points on the graph.
How can you tell if a graph sHow is a function?
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.
What is the math symbol for incongruency?
Three vertical lines, |, with a diagonal line across them.
How do you use the vetical line test to determine 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
