Answer:
B. A and D
Step-by-step explanation:
In each of the tables, the x-values differ by 1. So, a linear relation will have the y-values differ by a constant amount. We observe the differences to be ...
A: 3, 3, 3 . . . . a constant, so this function is linear
B: 1, 3, 5 . . . . not a constant; non-linear
C: 1, -6, 13 . . . not a constant; non-linear
D; 0, 0, 0 . . . a constant, so this function is linear
Tables A and D represent linear functions.
