Is this relation a function? The following discussions and activities are designed to lead the students to explore the the vertical line test for functions. If any vertical line intersects a graph more than once, the relation represented by the graph is 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. However, the set of all points [latex]\left(x,y\right)[/latex] satisfying [latex]y=f\left(x\right)[/latex] is a curve. The only graph given that passes the vertical line test is Y. The Vertical Line Test is a visual test that you can use to quickly check and see if a graph represents a function. If there is any such line, determine that the function is not one-to-one. The third graph does not represent a function because, at most x-values, a vertical line would intersect the graph at more than one point. 289 lessons f(x) = (x/4)-3 The vertical line test is used to determine whether a function the number obtained when applying f to the x-coordinate. If the function is defined for only a few input values, then the graph of the function is only a few points, where the x-coordinate of each point is an input value and the y-coordinate of each point is the corresponding output value. In physics, engineering and construction, the direction designated as vertical is usually that along which a plumb-bob hangs. B. a vertical line. The curve shown includes [latex]\left(0,2\right)[/latex] and [latex]\left(6,1\right)[/latex] because the curve passes through those points. A function maps each domain element to only one range element. Hint to this test: The graph of a function f is the set of all points whose y-coordinate equals f (x), i.e. (0,0) absolute maximum: 3 absolute Let’s explore the relationship between points on a line and the slope of the line.

The graph does not pass the vertical line test; therefore, the graph is not a function, and it is a relation only. The most common graphs name the input value [latex]x[/latex] and the output value [latex]y[/latex], and we say [latex]y[/latex] is a function of [latex]x[/latex], or [latex]y=f\left(x\right)[/latex] when the function is named [latex]f[/latex]. This quiz/worksheet combination will assess your grasp on functions, the efficacy of the vertical line test and when you might use this test. Notice that any vertical line would pass through only one point of the two graphs shown in parts (a) and (b) of Figure 13. All rights reserved. 12. When they get an answer, they put an X over it on their board. If you think about it, the vertical line test is simply a restatement of the definition of a function.
