For which values of k is the set of order pairs (2, 4), (, 6), (4, 0 ) a function?​

Sagot :

So k=/= 2,4

The answer is elements of all real numbers where k is not equal to 2 and 4.

In set builder notation:

{ xER | x =/= 2,4 }

***There's a special symbol for that E there and the R (real numbers). I am only using my phone so I wasn't able to put the correct symbols.
