Why cant a vertical line pass through a function more than once?

Because a function is defined as having distinct outputs for every input therefore... you can never have two values for one x value and you can see this relationship by drawing a vertical line.

How can you tell if a graph show a FUNCTION?
By doing a vertical line test. If you can draw a vertical line and it only passes through the graph once, its a function. If it passes through twice, it is NOT a function.
Can a parabola represent a function?
If a vertical line passes through the supposed function at only one spot then you have a function.
How can you tell if a graph that represents the relationship is a function?
The vertical line test! Imagine a vertical line going through all points of the graph. As long as the vertical line only touches the graphed line once, it's a function. If it touches more than once, it is not.
What do you call a function whose graph is a non-vertical line?
It is a function. If the graph contains at least two points on the same vertical line, then it is not a function. This is called the vertical line test.
A function will always be a vertical line?
A function can never be a vertical line, because it then fails the definition of a function: every x value outputs only 1 y value. The vertical line test will determine if a relation is a function. If a vertical line intersects the graph of the function at more than one place, it is not a function.

How do you determine weather the graph represent a function?
The "vertical line test" will tell you if it is a function or not. The graph is not a function if it is possible to draw a vertical line through two points.
Which type of line that tests for a function?
Vertical line. If you can draw a vertical line through some part of a graph and it will intersect with the graph twice, the graph isn't a function.
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
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.
Can a parabola represent a function?
If a vertical line passes through the supposed function at only one spot then you have a function.
When is it not a function?
A function is not a function if it passes through the vertical line test more than once, and it is not linear or a quadratic.
How can you tell if a graph that represents the relationship is a function?
The vertical line test! Imagine a vertical line going through all points of the graph. As long as the vertical line only touches the graphed line once, it's a function. If it touches more than once, it is not.
What are the functions in storage tanks?
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'.)
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.
