Answer:

  1. no
  2. yes
  3. no
  4. no
  5. no
  6. yes

Step-by-step explanation:

If a vertical line can be made to intersect the graph at more than one point, the relation is not a function.

Relations 1, 3, 4, 5 have points one above another, so are not functional relations.

Relations 2 and 6 pass the vertical line test, so are functional relations.
