The test is: If you were to draw a vertical line through every point in the domain (every x-value that is allowed), would it intersect the graph in exactly one point? Rather than draw lines, you could just slide a ruler, keeping it parallel to the vertical (y) axis.
If no intersection, then it is not a function because there is a point in the domain which has no image in the range.
If more than one intersection, then it is not a function because there is a point in the domain that is mapped to more than one value in the range.

What is the test that determines if a graph is a function?
The vertical line test determines if a graph represents a function. If a vertical line intersects the graph at more than one point, the graph does not represent a function, as this indicates that a single input (x-value) corresponds to multiple outputs (y-values). Conversely, if every vertical line intersects the graph at most once, it confirms that the graph is a function.
What is the horizantal line test and vertical line test?
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.
The graph of a function must pass the line test?
The line test, often referred to as the vertical line test, states that for a graph to represent a function, any vertical line drawn on the graph must intersect it at most once. This ensures that for every input (x-value), there is exactly one output (y-value). If a vertical line intersects the graph at more than one point, the relation is not a function. Therefore, passing the line test is a fundamental characteristic of a function's graph.
What is a way to see if a line on a graph is a function?
To determine if a line on a graph represents a function, you can use the vertical line test. If any vertical line drawn through the graph intersects the line at more than one point, then it is not a function. Conversely, if every vertical line intersects the graph at most once, it confirms that the line is indeed a function. This test helps ensure that each input (x-value) corresponds to exactly one output (y-value).
What is The test to determine if a graph is a function is?
A graph is represents a function if for every value x, there is at most one value of y = f(x).
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.
Recall that the vertical line test is used to check whether a particular graph represents the graph of a function what are correct statements for this graph?
This graph fails the vertical line test at x = 3This graph is not the graph of a function.
Is an oval a graph of a function?
No, the graph of an oval/ellipse is not a function because it does not pass the vertical line test.
Why would you use the vertical line test?
To see if a graph is a function. There is only one x for every y!
What is the axis of symmetry of the function shown in the graph?
I regret that I can see no function shown.

How can you tell if a graph 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.
Is y equals -x cubed plus 1 a function?
Yes, y = -x3+1 is a function. You can graph it and see that it passes the vertical line test. See related link, below.
