WebRecall that the Horizontal line test tells you if the graph is likely to be invertible. 6 : Consider the following graph. Does this graph represent a function? Yes. No. Although this may look like it has a vertical segment right near the origin, it in fact doesn’t. This is a good example of why graphing can be a bit misleading at times. WebA test use to determine if a function is one-to-one . If a horizontal line intersects a function's graph more than once, then the function is not one-to-one. 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.

WebThe 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: 2 If no horizontal line intersects the function in more than one point, the function is one-to-one (or injective ). WebMay 3, 2024 · A horizontal line intersects the graph of an injective function at most once. Proof. Suppose otherwise. Then there exists a horizontal line y = k and an injective function f whose graph intersects the line y = k at two points, ( x 1, k) and ( x 2, k), with x 1 < x 2. Then f ( x 1) = f ( x 2) = k.
