Step-by-step explanation:

Example:

1233

x 7888

A

Step-by-step explanation:

you do that because you need to carry the numbers and you get a much better answer.

  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.

the anwser is d) 75°
