Answer:

Yes, no two ordered pairs in this list has the same second element.

Step-by-step explanation:

The function is a relation that associates to different elements [tex]x_1[/tex] and [tex]x_2[/tex] different elements [tex]y_1[/tex] and [tex]y_2.[/tex]

Given K = {(-3, -3), (-4, -4), (-5, -5), (-6, -6)}

So,

  • [tex]x_1=-3\rightarrow y_1=-3;[/tex]
  • [tex]x_2=-4\rightarrow y_2=-4;[/tex]
  • [tex]x_3=-5\rightarrow y_3=-5;[/tex]
  • [tex]x_4=-6\rightarrow y_4=-6.[/tex]

Since different x have different image points y, this relation is the function. The correct answer is "Yes, no two ordered pairs in this list has the same second element."

Answer:

Yes, no two ordered pairs in this list has the same first element.

x values can only have one y value

different x values CAN have the same y value ex (3,3) (4,3).
