Pls help There are 2 chicken ordered for every 5 steak Y= # of chicken orders X= # … x Video is suitable for 6th - 11th Grade. 1 − vertical line intersects the graph exactly once, except. . 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. If no two different points in a graph have the same first coordinate, this means that vertical lines cross the graph at most once. This is known as the vertical line test. 00:00; 00:00 / 00:00; CC. 1 A vertical line test is a visual way to determine if the graph of a relation is a function using a vertical line. This method is use to find if the graph shows or not a function. ≤ Vertical Line Test: The vertical line test is used to determine if a graph is a function by using a line that is parallel to the y-axis that intersects the graph. If you think about it, the vertical line test is simply a restatement of the definition of a function. The vertical line test can be used to determine whether a graph represents a function.
