Web4 CS 441 Discrete mathematics for CS M. Hauskrecht Equality Definition: Two sets are equal if and only if they have the same elements. Example: • {1,2,3} = {3,1,2} = {1,2,1,3,2} Note: Duplicates don't contribute anythi ng new to a set, so remove them. The order of the elements in a set doesn't contribute WebExample: y = x 3. The input set "X" is all Real Numbers; The output set "Y" is also all the Real Numbers; We can't show ALL the values, so here are just a few examples: X: x Y: x 3-2-8 ... so a function can also be seen as a set of ordered pairs . 5571, 5572, 535, 5207, 5301, 1173, 7281, 533, 8414, 8430.

Webthen we use a different object called ordered pair, represented (a,b). Now (a,b) 6= (b,a) (unless a = b). In general (a,b) = (a0,b0) iff a = a0 and b = b0. Given two sets A, B, their … Web(b) Write the equivalence relation as a set of ordered pairs. Answer Summary Review A relation R on a set A is an equivalence relation if it is reflexive, symmetric, and transitive. If R is an equivalence relation on the set A, its equivalence classes form a partition of A.
WebB = {2, 7} Then the Cartesian Product of A and B (written as "A x B") is the set: A x B = { (a,2), (a,7), (b,2), (b,7), (c,2), (c,7)}, where each element of the set is an ordered pair of elements. … WebApr 24, 2024 · Definitions. A partial order on a set S is a relation ⪯ on S that is reflexive, anti-symmetric, and transitive. The pair (S, ⪯) is called a partially ordered set. So for all x, y, z ∈ S: x ⪯ x, the reflexive property. If x ⪯ y and y ⪯ x then x = y, the antisymmetric property.

Web• A function f from a set A to a set B is a set of ordered pairs {(x,y)} such that x in the set A and y is the in the B. For every x ∈ A there is exactly one y ∈ B such that (x,y) is an ordered pair in f. We call this element f(x). We call A the domain and we call B the range. • How can we think of a function as an operation on the input?
WebDec 23, 2024 · The first set of ordered pairs is a function, because no two ordered pairs have the same first coordinates with different second coordinates. The second example is not a function, because it ... flowertop coal ironWebAn ordered pair, as is typically meant in beginning algebra (though there are some more advanced meanings you'll get into later), is the x and y coordinates of a point, stated in that order. Thus, (3,4) is the ordered pair representing the point at x=3 and y=4. (4,3) is not the same, that is the point at x=4 and y=3. flower toolsWebAn ordered pair is a pair of numbers in a specific order. For example, (1, 2) and (- 4, 12) are ordered pairs. The order of the two numbers is important: (1, 2) is not equivalent to (2, 1) -- (1, 2)≠ (2, 1).
