In your example R = R 2 so that ∂ R = ∅. Consequently R ∩ ∂ R = ∅ as well as ∂ R ⊆ R. So R is open and closed. There is no r ∈ R such that R = R ⊆ { x, y ∈ R 2 ∣ x 2 + y 2 ≤ r 2 }.

WebJul 7, 2024 · Definition: surjection. A function f: A → B is onto if, for every element b ∈ B, there exists an element a ∈ A such that f(a) = b. An onto function is also called a surjection, and we say it is surjective. Example 6.4.1. The graph of the piecewise-defined functions h: [1, 3] → [2, 5] defined by. WebIn general, the set of all real numbers (R) is considered as the domain of a function subject to some restrictions. They are: When the given function is of the form f (x) = 2x + 5 or f (x) = x 2 – 2, the domain will be “the set of all real numbers.
