Injectivce functio
WebbInjective, Surjective and Bijective "Injective, Surjective and Bijective" tells us about how a function behaves. A function is a way of matching the members of a set "A" to a set … WebbA function is injective, or one to one, if each horizontal line intersects the graph of a function at most once. A function is not injective, or one to one, if there is a horizontal line that crosses its graph more than once. This is similar to the vertical line test that is used to verify the definition of a function.
