Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.

PROBLEM 7: Binary Relations, Functions and Orderings (15 pts) 1. (2 pts) Prove that ({2, 3, 4, 6, 24, 36, 72}, /) is a poset, create its corresponding Hasse diagram and identify maximal and minimal elements. 2. (1 pts) Prove that (P{1, 2, 3}, C) is a poset, create its corresponding Hasse diagram and identify maximal and minimal elements 3. Assume the following mapping, captured by variable map: map = { 72 {1,2,3}, 36 {3}, 24 {1,2}, 6- → {3}, 4 {1,3}, 2➡ {} } Provide answers to the following in detail (in plain english and formally): (a) (2 pts) Is variable map a function? If so, is it a total or a partial function? Identify domain and codomain. (b) (10 pts) Discuss all properties (injectivity, surjectivity, bijection, order preserving, order reflecting, order embedding, isomorphism). NOTE: When we reason formally on a property we must state: (1) What Law do we expect to hold or not hold, and (2) Does this Law indeed hold or Is this Law violated?
