Answer:
The table can be filled as shown below.
Step-by-step explanation:
The first function is

Put different values of x and find values of f(x).
For x=-2

For x=-1

Similarly for x=0,1,2 the value of f(x) are 8,12,16 respectively.
The second function is

For x= -6

For x= -3

Similarly for x=0,3,6 the value of f(x) are 8,10,12 respectively.
The third function is

For x= 2

For x= 3

Similarly for x=4,5,6 the value of f(x) are 32,132,632 respectively.
The fourth function is

For x=-4

For x=-3

Similarly for x=-2,-1,0 the value of f(x) are 11,-1,-4 respectively.
