Horizontal definition, at right angles to the vertical; parallel to level ground. ; f is bijective if and only if any horizontal line will intersect the graph exactly once. Its cousin is the vertical line which runs up and down the page. Join now. 1. In mathematics, the vertical line test is a visual way to determine if a curve is a graph of a function or not. Join now. Which year the horizontal line is discovered Get the answers you need, now! Median response time is 34 minutes and may be longer for new subjects. A function can only have one output, y, for each unique input, x.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. For each element in the range if there exist exactly one element in the domain the function is said to be one to one. Step-by-step explanation: Topic namin yan dati. Meaning of VERTICAL LINE TEST. !Answer :-In a graph the horizontal line is called x-axis Vertical is Y -axis.#HOPE IT HELPS â¢ Always perform the horizontal line test after the vertical line test. See more. Then the function is one-to-one. Log in. What does horizontal mean? 1. Horizontal Line Test. If we were talking about a horizontal line, then we'd say y doesn't change. This is when you plot the graph of a function, then draw a horizontal line across the graph. - 15110629 Note: The function y = f(x) is a function if it passes the vertical line test.It is a one-to-one function if it passes both the vertical line test and the horizontal line test. A horizontal line in a distance time garph represent the time take to cover the distance Trippienaee Trippienaee 06.10.2020 Physics Secondary School What Does a horizontal line represent in a distance time graph? A graph of a function can also be used to determine whether a function is one-to-one using the a. vertical line test b. horizontal line test The horizontal line test, which tests if any horizontal line intersects a graph at more than one point, can have three different results when applied to functions: 1. 1. 2 See answers bindogirl6115 bindogirl6115 Explain why the vertical line test is used to determine if a graph represents a function. One very important classification is deciding whether a function is one-to-one. If every horizontal line cuts the graph in at most one point, then the function has an inverse otherwise it does not. b) c)
