Table B
Step-by-step explanation:
Table A Input Output
5 3
5 2
4 1
Has an input that goes to 2 different outputs, not a function
Table B Input Output
1 2
3 2
5 3
one to one relation which is a function
Table C Input Output
0 0
1 2
1 3
Has an input that goes to 2 different outputs, not a function
Table D Input Output
4 2
4 3
4 4
Has an input that goes to 2 different outputs, not a function
The domain of F(x) is all real numbers.
This is due to the fact that the function has no undefined points or domain constraints.
Answer:
1.133 is about 1, 7.684 is about 8, and 4.718 is about 5. Thus, 1 + 8 + 5 = about 14.
