Step-by-step solution

The problem requires us to identify a table corresponding to the function described by Y=X3 Y = X - 3 . We will calculate Y Y for each X X provided in the choices.

Applying the formula, for choice 1 where X=0,1,2 X = 0, 1, 2 :

  • If X=0 X = 0 , then Y=03=3 Y = 0 - 3 = -3 .
  • If X=1 X = 1 , then Y=13=2 Y = 1 - 3 = -2 .
  • If X=2 X = 2 , then Y=23=1 Y = 2 - 3 = -1 .

For choice 2 where X=2,4,6 X = 2, 4, 6 :

  • If X=2 X = 2 , then Y=23=1 Y = 2 - 3 = -1 .
  • If X=4 X = 4 , then Y=43=1 Y = 4 - 3 = 1 .
  • If X=6 X = 6 , then Y=63=3 Y = 6 - 3 = 3 .

For choice 3 where X=2,5,8 X = 2, 5, 8 :

  • If X=2 X = 2 , then Y=23=1 Y = 2 - 3 = -1 .
  • If X=5 X = 5 , then Y=53=2 Y = 5 - 3 = 2 .
  • If X=8 X = 8 , then Y=83=5 Y = 8 - 3 = 5 .

For choice 4 where X=8,6,4 X = -8, -6, -4 :

  • If X=8 X = -8 , then Y=83=11 Y = -8 - 3 = -11 .
  • If X=6 X = -6 , then Y=63=9 Y = -6 - 3 = -9 .
  • If X=4 X = -4 , then Y=43=7 Y = -4 - 3 = -7 .

Choosing from these computations, the first table matches the description Y=X3 Y = X - 3 , where for X=0,1,2 X = 0, 1, 2 gives Y=3,2,1 Y = -3, -2, -1 respectively.

Therefore, the table corresponding to the function description is choice 1.
