Please help. I also will post another question I need help with. Thank you if you help.

Geometric progression, first term 5, common ratio 3.

5, 15, 45, 135

  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.
