Oxandy

Oyandx

Time and volume

O volume and time

Answer 1

8. Identify the domain and the range of each of the following relations

[[4.2, 1.5], [5, 2.2], [7, 4.8], [4.2, 0]]

Odomain (1.5, 2.2, 7, 4) range (4.2, 5, 4.8, 0)

Odomain (4.2, 5, 7, 4) range (1.5, 2.2, 4.8, 0)

Odomain (1.5, 2.2, 4.8, 0) ) range ( 4.2, 5, 7, 4

Answer 2

In the given graph, the variables are:

1. Ox axis (x-axis): Time
2. Oy axis (y-axis): Volume of Pool Water

Answer 3

The domain is the set of all the x-values in the relation, and the range is the set of all the y-values.

Given the relation [[4.2, 1.5], [5, 2.2], [7, 4.8], [4.2, 0]], we can identify the domain and range as follows:

Domain: The x-values in the relation are 4.2, 5, and 7. Therefore, the domain is (4.2, 5, 7).

Range: The y-values in the relation are 1.5, 2.2, 4.8, and 0. Therefore, the range is (1.5, 2.2, 4.8, 0).

So, the correct answer is: Domain (4.2, 5, 7) and Range (1.5, 2.2, 4.8, 0).
