Answer:
The top box: 3
The middle box: 2
The bottom box: 1
Step-by-step explanation:
In order to fill out the yellow boxes we have to use the equation above the table, and plug in the x values, and so we get...
If x = 2, then
y = x + 1
y = 2 + 1
y = 3
If x = 1, then
y = x + 1
y = 1 + 1
y = 2
If x = 0, then
y = x + 1
y = 0 + 1
y = 1
