Question

Part 1 : Create a Relation

Answer 1

(1,5) , (2,6) , (3,7) , (4,8) , (5,9)....these are the 5 points

  x               f(x)
  1                5
  2                6
  3                7
  4                8
  5                9

domain (ur x values) is { 1,2,3,4,5}
range (ur f(x) or y values) is { 5,6,7,8,9}

Is ur relation a function : yes, it is a function. A function will not have any repeating x values. It can have repeating y values, just not the x ones.
