Which is -12/5 now flip it to get the (MI) which is -5/12

Which equals 1

Mrrafil [7]

9514 1404 393

Answer:

  8, 12

Step-by-step explanation:

The x-values of a function cannot repeat. That is, the x-values already in the table, {3, 6, 7, 9}, cannot be used again. Any added x-values must be different from these if your relation is to remain a function.

Of the choices offered, only 8 and 12 can be used for added x-values.
