Given:
3.
[tex]\lbrace(5,8),(-5,-2),(4,-6),(-5,-1),(-4,-5)\rbrace[/tex]
8.
[tex]\lbrace(-6,-1),(-4,8),(5,-4),(-3,-3),(-9,1)\rbrace[/tex]
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:
[tex]\lbrace(5,8),(-5,-2),(4,-6),(-5,-1),(-4,-5)\rbrace[/tex]
Based on the above information, the answers would be:
Domain:
[tex]\lbrace-5,-4,4,5\rbrace[/tex]
Range:
[tex]\lbrace-6,-5,-2,-1,8\rbrace[/tex]
Function: Question 3 is not a function because the -5 value which is an x value appeared twice.
Question 8:
[tex]\lbrace(-6,-1),(-4,8),(5,-4),(-3,-3),(-9,1)\rbrace[/tex]
Domain:
[tex]\lbrace-9,-6,-4,-3,5\rbrace[/tex]
Range:
[tex]\lbrace-4,-3,-1,1,8\rbrace[/tex]
Function: Question 8 is a function because every input has exactly one output.
