Using vertical line test, we can figure out whether a given curve is the graph of a function or not. A relation is a function if there are no vertical lines that intersect the graph at more than one point. If you have 2 or more x coordinates that are the same - they must all have the same output or it is not a function. Even though each y coordinate is mapped to two x coordinates (y = 1 is mapped to x = 1 and x = -1) except 0, no x coordinate is mapped to two y coordinates. Report an issue . • Example 2: Similarly, the circle is not the graph of a function, since a vertical line can intersect the circle twice. • a minute ago by. A function f can have only one value f(x) for each x in its domain. If a vertical line intersects a curve on an xy-plane more than once then for one value of x the curve has more than one value of y, and so, the curve does not represent a function. A function f can have only one value f(x) for each x in its domain. A function can only have one output, y, for each unique input, x.

Draw a vertical line cutting through the graph of the relation, and then observe the points of intersection. The vertical line test supports the definition of 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. Use the vertical line test! Mathematics. Quiz. Is each input only paired with only one output? Vertical Line Test: A function takes every value in its domain and assigns to it a unique value in its range. If a is in the domain of the function f, then the vertical line x=a will intersect the graph of f at the single point (a,f(a)). Report an issue .
