1. Which number is not an element of the domain of the given relation? {(-2,4), (0,4), (1,2), (3,2)}

2. A function of x containing four ordered pairs of the form (x, y) is shown below:

{(2,3), (4,5), (6,7), (8,9)}

What is the domain of the function?

3. Which number is not an element of the range in the relation shown?

{(4, -1), (-1, 5), (-4, 1), (-5, 4)}

4. A function of x containing four ordered pairs of the form (x, y) is shown below:

{(2,0), (4, 0), (6,0), (8,0)}

What is the range of the function?

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
