WebMar 23, 2024 · If you have an equation that's already written in terms of y and x (for instance, 2 + y = 3x 2 ), all you need to do is solve for y by isolating it on one side of the equals sign. [2] Example: If we have a function f (x) = 5x - 2, we would rewrite it as y = 5x - 2 simply by replacing the "f (x)" with a y. WebBy definition let f a function from set X to Y. f is surjective if for every y in Y there exists an element x in X such that f(x) = y. f is injective if the following holds x = y if and only if f(x) = f(y).
