Find the domain and range of the relation and determine whether it is a function.
domain: positive integers; range: positive integers; no, it is not a function.
domain: x > 3; range: y > 0; yes, it is a function.
domain: all real numbers; range: all real numbers; yes, it is a function.
domain: x ³ 0; range: y > 3; no, it is not a function.

  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.
