Graphs That Represent Not A Function. If we can draw any vertical line that intersects a graph more than once then the graph does not define a function because a function has only one output value for each input value. Solve it with our calculus problem solver and calculator.
If any vertical line intersects the graph more than once then the graph does not represent a function. That graph looks like this. The graph would look like this.
The graph of y sqrt x would be a relation because each value of x can have more than one value of y.
Use on a graph to determine if the graph represents a function. The latex x latex value of a point where a vertical line intersects a function represents the. The vertical line test can be used to determine whether a graph represents a function. That graph looks like this.
