If K = {(x, y) Ix-y=5), is Set K a function?
1. Νο
2. Yes

no its not

Step-by-step explanation:

No k is not a function. The answer is A or 1

Step-by-step explanation:

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
