no it won't

In fact a function can NEVER be vertical. Not only that, it cannot loop back so that two (or more) points are above one another. For a function, there can be at most one y-value for any x-value so any vertical line will intersect the function at most once.

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.


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.


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.


Does a sideways parabola represent a function?

No, it does not. You can tell if something is a function or not by using the vertical line test. If there is more than one point at any vertical line, it is not a function.


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 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.


Can a line be a graph of a function?

Yes the graph of a function can be a vertical or a horizontal line


Can a line be the graph of a function?

Yes the graph of a function can be a vertical or a horizontal line

no


How can you tell if a function is a function?

The vertical line test can be used to determine if a graph is a function. If two points in a graph are connected with the help of a vertical line, it is not a function. If it cannot be connected, it is 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


Does a sideways parabola represent a function?

No, it does not. You can tell if something is a function or not by using the vertical line test. If there is more than one point at any vertical line, 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.
