WebThe horizontal line test is used to determine whether a function is one-one when its graph is given. We have already seen the condition (g (x 1) = g (x 2) ⇒ x 1 = x 2) to determine whether a function g (x) is one-one algebraically. On the other hand, to test whether the function is one-one from its graph, WebIn an injective function, every element of a given set is related to a distinct element of another set. A function f : X → Y is defined to be one-one (or injective), if the images of distinct elements of X under f are distinct, i.e., for every x1, x2 ∈ X, there exists distinct y1, y2 ∈ Y, such that f(x1) = y1, and f(x2) = y2. csn chem 103WebFind the best open-source package for your project with Snyk Open Source Advisor.
