To determine which table does not represent a function, we need to check if any x-value has more than one corresponding f(x) value.
-
Table A:
- x = 0 → f(x) = 1
- x = 2 → f(x) = 3
- x = 3 → f(x) = 4
- x = 4 → f(x) = 5
- x = 5 → f(x) = 6
- x = 6 → f(x) = 7
- (All x-values are unique)
-
Table B:
- x = -3 → f(x) = 9
- x = -2 → f(x) = 4
- x = -1 → f(x) = 1
- x = 0 → f(x) = 0
- x = 1 → f(x) = 1
- x = 2 → f(x) = 4
- (Unique x-values)
-
Table C:
- x = 0 → f(x) = 3
- x = 2 → f(x) = 3
- x = 3 → f(x) = 3
- x = 4 → f(x) = 3
- x = 5 → f(x) = 3
- x = 6 → f(x) = 3
- (All x-values are unique)
-
Table D:
- x = 0 → f(x) = -1 and f(x) = 4 and f(x) = 6 → (x = 0 maps to multiple values)
- x = 2 → f(x) = 3 and f(x) = 5 and f(x) = 7 → (x = 2 also maps to multiple values)
From this analysis, Table D does not represent a function because it has x-values that correspond to multiple f(x) values.
So the answer is D (DD).
