Identify the domain and range of the relation. Represent the relation with amapping diagram. Is the relation a function?
{(−1, 1), (−2, 2), (4, −4), (7, −7)}

Answers

Answer 1
Answer:

The domain and range of the relation {(-1, 1), (-2, 2), (4, -4), (7, -7)} are {-1, -2, 4, 7} and {1, 2, -4, -7} respectively.

What is relation in function?

Not every relation is a function, but every function is a relation.

A function is a relation with clear boundaries.

When we say that something is well-defined, we mean that each element has been assigned a specific image.

The given set is,

{(-1, 1), (-2, 2), (4, -4), (7, -7)}

The domain of a set is the values of x,

Domain = {-1, -2, 4, 7}

The range of a set is the values of y,

Range = {1, 2, -4, -7}

The relation makes the function because for every value of x the sign of function y is negative,

The required function is,

y = -x.

Prime numbers have only 2 factors 1 and its number for example:
2, 3, 5, 7, 11, 13, 17, 19, 23

Composite numbers have more than two factors for example :
0, 4, 6, 8, 9, 10, 12, 14 15, 16..

For example 0 has many factors
0 times 3 0times 4

Step-by-step explanation: You know that it is a prime if the only number divisible by the number is one. If there are more numbers than 1 then it is composite.


What ratio is equivalent to 10/14

Answers

Divide the numerator and the denominator by 2.

(10~divided~by~2)/(14~divided~by~2) = (5)/(7)

(5)/(7) or 5:7 is equivalent to (10)/(14)
to find an eqivalent ration the denominator and numerator have to be both mutiplied or dvided by the same number. 
For example: 10 time 2 = 20
14 times 2 = 28 
so 20/28 is equivalent to 10/14 :)
