Exam. Pages 4. 0000030146 00000 n Watch the video or read on below: It works in a similar way to the vertical line test, except you (perhaps, obviously) draw horizontal lines instead of vertical ones. 0000037239 00000 n for those that do—the Horizontal Line Test for an inverse function. Horizontal Line Test. One simple example of a one-to-one function (often called an injectivefunction) is with the daily specials at a restaurant.

Such as (y = 5, y = - 3, y = 17, etc.) The graph of the function given by is shown in Figure 1.97. –5 5 5 x y f(x) = Ë25 – x2 0 (–3, 4)(3, 4) Figure 3 As illustrated in Example 1(b), a way to show that a function is not one-to-one is to produce a pair of different domain elements that … Example 4 : … Alleen Test Solutions. They are drawn from left to right through the y-axis. A horizontal line proceeds from left to right on a chart, or parallel to the x-axis. The graph of y = sin x does not pass the horizontal line test, so it has no inverse. Determine if function or not function. %PDF-1.5 0000007690 00000 n The Maddox rod test can be used to subjectively detect and measure a latent, manifest, horizontal or vertical strabismus for near and distance. 0000036392 00000 n Let's say your function has the ordered pair (4,5). <> Wednesday - Steak 5.
