If for every point on the horizontal axis, the graph has one and only one point corresponding to the vertical axis; then it represents a function.
Functions can not have discontinuities along the horizontal axis. Functions must return unambiguous deterministic results.

What can be used to determine if a graph represents a function?
If the graph is a function, no line perpendicular to the X-axis can intersect the graph at more than one point.
What is function if X is -1 and y is 4?
It is impossible to determine the function here. (-1,4) is just a point on a graph.
Is a circle graph a function?
No, a circle graph is never a function.
What line test is used to determine if a graph is a 1-1 function?

How can you tell if a graph is a sine function or a cosine function?
sine graph will be formed at origine of graph and cosine graph is find on y-axise
How can one determine the median from a graph?
The answer depends on what the graph is of: the distribution function or the cumulative distribution function.
What can be used to determine if a graph represents a function?
If the graph is a function, no line perpendicular to the X-axis can intersect the graph at more than one point.
How do you determine if a relation represents a function?
If the function is a straight line equation that passes through the graph once, then that's a function, anything on a graph is a relation!
How can you determine if a relationship between two variables is a function from a graph?
The relationship is a function if a vertical line intersects the graph at most once.
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 determine whether a graph of a mathematical relationship is a function?
If a vertical line, within the domain of the function, intersects the graph in more than one points, it is not a function.
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 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.
How do you determine whether a graph a mathematical relationship is a function?
Draw a vertical line if the line hits more than one point on the graph then it is not a function.
How can you tell whether a graph is a function or not?
A vertical line test can be used to determine whether a graph is a function or not. If a vertical line intersects the graph more than once, then the graph is not a function.
What is function if X is -1 and y is 4?
It is impossible to determine the function here. (-1,4) is just a point on a graph.
How can you tell if a graph is a function?
A graph is a function if every input (x-value) corresponds to only one output (y-value). One way to check for this is to perform the vertical line test: if a vertical line intersects the graph at more than one point, the graph is not a function.
