Question

Part A and Part B solve the expression then compare and contrast

Answer 1

Given:

3.

`\lbrace(5,8),(-5,-2),(4,-6),(-5,-1),(-4,-5)\rbrace`

8.

`\lbrace(-6,-1),(-4,8),(5,-4),(-3,-3),(-9,1)\rbrace`

To compare and contrast the given above, we must note the following:

Domain- x coordinates

Range- y coordinates

Function- Our answer would be yes or no. We must also note that a function is a relation in which every input has exactly one output.

For Question 3:

`\lbrace(5,8),(-5,-2),(4,-6),(-5,-1),(-4,-5)\rbrace`

Based on the above information, the answers would be:

Domain:

`\lbrace-5,-4,4,5\rbrace`

Range:

`\lbrace-6,-5,-2,-1,8\rbrace`

Function: Question 3 is not a function because the -5 value which is an x value appeared twice.

Question 8:

`\lbrace(-6,-1),(-4,8),(5,-4),(-3,-3),(-9,1)\rbrace`

Domain:

`\lbrace-9,-6,-4,-3,5\rbrace`

Range:

`\lbrace-4,-3,-1,1,8\rbrace`

Function: Question 8 is a function because every input has exactly one output.
