Sketch a digraph for a relation on the set {a, b, c, d} that is irreflexive and symmetricbut not transitive.
let A = { 1, 2, 3, 4, 5} and B = { a, b, c, d, e, f}. in each case, give an example of a function f : A-->B with indicated properties, or explain why no such function exist. a) f : A--->B, f is one-to-one b) g: B--> A, g is one-to-one c) f : A---> B, f is onto d) g: B-->A, g is onto
If A is set of different triangles in the plane and B is set of all positive real numbers. A relation R is defined from set 4 to set B such that every element of set A is associated with some number in set B which is measure of area of triangle. Is this relation as function?
Given any set of 15 integers, must there be two that have the sameremainder when divided by 12? Prove using the pigeonhole principle. Eitherdescribe the pigeons, the pigeonholes, and how the pigeons get to the pigeonholes, or describe a function by giving its domain, co-domain, and how elements of the domain are related to elements of the co-domain.
Suppose f: A --> B is a function. Define the function F: P(B) --> P(A) (from the powerset of B to the one of A) by setting F(S) = f-1(S) for all S subset of B. Prove or disprove: (1) F is 1-1 if and only if f is onto. (2) F is onto if and only if f is 1-1. [Finite, not infinite.]
