In order to be a function, each x value can only be paired with exactly one y value. If the vertical line passes through at least two points on the graph, then an element in the domain is paired with more than 1 element in the range. A function f can have only one value f(x) for each x in its domain. Note: If you don’t know what a function is, you may want to read the function definition first.. Why does this work? As a result, the relation is not a function. The vertical line test supports the definition of a function. Is this a function?

Mathematics. Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. This means that when x is 4, the y must be 5. A function f can have only one value f(x) for each x in its domain. View vertical line test.pdf from MATH 111 at Jackson State University. 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. Please enable Cookies and reload the page. Is this a function? Vertical Line Test: A function takes every value in its domain and assigns to it a unique value in its range. So, no vertical line can intersect the graph of a function more than once. No

Tags: Question 22 . A vertical line is drawn for every value in the domain of relation and if that line only passes the relation once then the relation is a function. Even graphs need to worry about tests! 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)). If each line crosses the graph just once, the graph passes the vertical line test. If you can not, then the graph represents a function.
