- 1. Multiple ChoiceWhich of the following guarantees a table will not be a function?A x value repeatsAn y value repeatsAn x value repeats and has different y valuesA y value repeats and has different x values
- 2. Multiple Choice
Is this graph a function and how can you tell?Yes its a function cause it doesn't cross itselfNo it's not a function because it goes through the originNo it's not a function because the x value 4 has y values of -2 & 2No it's not a function because the y value 4 has x values of -2 & 2 - 3. Multiple ChoiceIs this mapping a function and how can you tell?Yes its a function cause all the numbers have linesNo it's not a function because there a 5 in both ovalsNo it's not a function because the x value 5 has y values of 2 & 9No it's not a function because the y value 5 has x values of 2 & 9
- 4. Multiple ChoiceIs this table a function and how can you tell?Yes its a function because there are not variables for missing numbersNo it's not a function because the y value 4 repeatedNo it isn't a function because the x value 2 is repeatedNo it's not a function because the x value 5 has y values of 10 & 12
