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.

How do the numerator and denominator of a fraction compare with the dividend and divisor of a division exxpression?
Answer:
length = 7.5 cm
Step-by-step explanation:
Volume of rectangular box = 60 cubic cm
length * width * height = 60
length * 4 * 2 = 60
length * 8 = 60
length = 60/8 = 7.5 cm
36.878 feet is the answer for it.
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.
