Question

For what value of k will the relation S = {(2k+3, 1), (3k−1, −2)} not be a function?

Answer 1

the answer is k=4 thanks for anything's

Answer 2

The relation will not be a function if the to ordered pairs have the same first value. That will happen when

... 2k+3 = 3k-1

... 4 = k . . . . . . add 1-2k

The relation will not be a function when k=4.
