Math Problem Statement
Consider the following tables, each representing a relation. Table #1: x = -2, -1, 0, 1, 2 and y = 2, 1, 0, -2, -1 Table #2: x = -2, -1, 0, 1, 2 and y = 0, 2, 1, -2, -1 Table #3: x = -2, -1, 0, 1, 2 and y = 1, 2, -2, 0, -1 A. Identify the two tables that represent relations that are inverses. (2 points) Table # and Table # For the table whose inverse was not given, create a table for its inverse. (Drag the provided options to the correct spots.) (5 points) (Here is table 4 already filled for the x) Table #4 x = -2, -1, 0, 1, 2 and you need to fill in the y = (Choices to put and sort out in order: -2, -1, 0, 1, 2)
Solution
Let's first review the tables given and check which ones represent inverse relations.
Table 1
x | -2 | -1 | 0 | 1 | 2 |
---|---|---|---|---|---|
y | 2 | 1 | 0 | -2 | -1 |
Table 2
x | -2 | -1 | 0 | 1 | 2 |
---|---|---|---|---|---|
y | 0 | 2 | 1 | -2 | -1 |
Table 3
x | -2 | -1 | 0 | 1 | 2 |
---|---|---|---|---|---|
y | 1 | 2 | -2 | 0 | -1 |
Step 1: Identify inverse relations
Two tables represent inverse relations if, for every pair in one table, the pair appears in the other table.
-
Table 1 and Table 2:
- Let's compare the pairs from Table 1 with Table 2.
- Table 1:
- Table 2:
We observe that the pairs match up exactly when the x and y values are swapped. Therefore, Table 1 and Table 2 are inverses.
-
Table 1 and Table 3:
- Table 1:
- Table 3:
The pairs do not match up as inverses because swapping the x and y does not lead to a consistent match between these tables. Therefore, Table 1 and Table 3 are not inverses.
-
Table 2 and Table 3:
- Table 2:
- Table 3:
These tables do not show inverse relationships either. Swapping the x and y values does not consistently result in corresponding pairs. Therefore, Table 2 and Table 3 are not inverses.
Step 2: Create the inverse for Table 3
We are now tasked with creating the inverse for Table 3. To do so, we need to swap the x and y values from the original table.
Table 3:
x | -2 | -1 | 0 | 1 | 2 |
---|---|---|---|---|---|
y | 1 | 2 | -2 | 0 | -1 |
Now swap the x and y values:
- For , the inverse pair will be
- For , the inverse pair will be
- For , the inverse pair will be
- For , the inverse pair will be
- For , the inverse pair will be
Thus, the inverse table (Table 4) will be:
x | -2 | -1 | 0 | 1 | 2 |
---|---|---|---|---|---|
y | -2 | -1 | 0 | 1 | 2 |
Final Answer:
- Table 1 and Table 2 represent inverse relations.
- The inverse of Table 3 is Table 4 with the y-values: -2, -1, 0, 1, 2.

Tip: To check if two relations are inverses, simply swap the x and y coordinates from one table and compare them to the second table. If they match, they are inverses!
