Not all of it fits but if someone could please help me with what they can I would really appreciate it!!

1.A≈78.54  2.A≈50.27 3. A≈201.34 4. A≈313.84

Step-by-step explanation:

answer: the common difference is -0.10

  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.
