{(−1, 1), (−2, 2), (4, −4), (7, −7)}
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.
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.

Mr. Galindo decided to take the family bowling. Which rational number represents the change in Mr. Galindo's bank account if he pays for three shoe rentals, three games of bowling and two large sodas?
Question 4 options:
$16.00
-$16.00
$-18.75
$18.75
Answer:
Step-by-step explanation:
Hello!
Alright, first, we will need to find the total of these items.
Shoe Rentals= $2.75
One Game of Bowling= $2.50
Large Soda: $1.50
The problem says he paid for three shoe rentals, three games of bowling, and two large sodas.
$2.75(3) + $2.50(3)+$1.50(2)=?
$8.25 + $7.50 + $3.00= $18.75
But it says which represents the change in his bank account after his purchase.
I believe your best answer here would be $-18.75
I hope this helps!
Step-by-step explanation:
1.) First, you need to find how many miles per hour (18), and how many miles (270)
2.) Next, you will need to divide 270 by 18, or 270/18.
3.) This will show you how many 18's you can get out of 270, or how many hours it will take to go 270 miles.
4.) After dividing, you will get 15.
Therefore, it will take you 15 hours to get from point A to point B.
