Answer:
C
Step-by-step explanation:
The table shows linear function.
Check it.
1. From x = 1 to x = 2 (change in x is +1), y changes from 6 to 8 (that is +2)
2. From x = 2 to x = 3 (change in x is +1), y changes from 8 to 10 (that is +2)
3. From x = 3 to x = 4 (change in x is +1), y changes from 10 to 12 (that is +2)
4. From x = 4 to x = 5 (change in x is +1), y changes from 12 to 14 (that is +2)
This means for constant change in x (+1) there is a constant change in y (+2), so the function represented by given table is linear.
