Answer: The description is mentioned in the below explanation.
Step-by-step explanation:
Since greatest integer function rounds down a real number to the nearest integer. for example, if f(x)=[x] and for x =1.3 f(x)= [1.3]= 1
or x= 0.9 f(0.9)= [0.9]= 0
Here, The given function, y=4[x+2]
Which is a greatest integer function and it is described on [0,3)
So, For the values of ,we take x=0 ⇒ y= 4(0+2)= 8
For, , we take x=1, ⇒ y = 4(1+2)= 12
For, we take x=2, ⇒ y = 4(2+2)=16
