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.


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 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.


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.
