Identify the function rule from the values in the table

Question

X. Y
6. 3
8. 4
10. 5
12. 6
Y=×-3
Y=x+3
Y=x+1
Y=x/2

Answer 1

To identify the function rule from the values in the table, we need to look for a pattern in the relationship between the values of x and y.

If we subtract 3 from each y-value, we get:

X. Y Y-3
6. 3 0
8. 4 1
10. 5 2
12. 6 3

We can see that the values in the Y-3 column are equal to the values in the X column. Therefore, the function rule is:

Y = X - 3
