Answer 1

Y=X+(X-3)

Explanation:

I did this exercise by looking at the table

From the numbers given. you can realize that to reach the Y every X number sums a quantity(ex 7+4=11/8+5=13/9+6=15)

if you create the equation Y=X+(X-3)---> then all the numbers in the box are correct. Its all a matter of trying until you realize is correct

EXAMPLESS

Y=X+(X-3)

11=7+(7-3)= CORRECT 11

13=8+(8-3)= CORRECT 13

15=9+(9-3)= CORRECT 15

17=10+(10-3)= CORRECT 17

when you do this you know the equation its ok and reflect the behaviour of the function.
