Definition 1: A relation is any subset of a Cartesian product. For instance, a subset of
, called a "binary relation from A to B," is a collection of ordered pairs (a,b) with first components from A and second components from B, and, in particular, a subset of
is called a "relation on A."
Definition 2: A function is a relation that associates each element x of a set X to a single element y of another set Y (possibly the same set). A function is uniquely represented by its graph which is the set of all ordered pairs (x, f (x)).
From these definitions you can see that every function is a relation from X to Y, but not via versa (because you can consider relation
- here for one x exist two y).
Answer: Correct choice is B.
Answer:
cubes are 3-d while squares are 2-d so in order to solve them you need different equations.
4200= 4.2 km so
4200 + 325= 4525 meters
jason ran 4525 meters
Answers: (y = 2) and (x = 1)
Steps:
Answer:
The answer to your question is 24x³ - 46x²- 28x + 63
Step-by-step explanation:
Data
(6x² - x - 9)(4x - 7)
Process
1.- Multiply 4x by the three terms of the first polynomial
(6x² - x - 9)(4x) = 24x³ - 4x² - 36x
2.- Multiply -7 by the three terms of the first polynomial
(6x² - x - 9)(-7) = -42x² + 7x + 63
3.- Add both result
24x³ - 4x² - 36x -42x² + 7x + 63 = 24x³ - 46x²- 28x + 63
