(surjective - f "covers" Y) Notice that all one to one and onto functions are still functions, and there are many functions that are not one to one, not onto, or not either.
Weba function relates inputs to outputs. a function takes elements from a set (the domain) and relates them to elements in a set (the codomain ). all the outputs (the actual values related to) are together called the range. a function is a special type of relation where: every element in the domain is included, and. Web1/x 1 = 1/x 2. Cross-multiply both sides of the equation to simplify the equation. x 2 = x 1. x 1 = x 2. We’ve just shown that x 1 = x 2 when f (x 1) = f (x 2 ), hence, the reciprocal …
