I just need help completing the table.

Step-by-step explanation:

Given the function f(x)=x-3

So we want to know the value of the function when

1. x=1

Then, f(x) =x-3

Let substitute x=1

f(1)=1-3

f(1)=-2

2. x=2

Then, f(x) =x-3

Let substitute x=2

f(2)=2-3

f(2)=-1

3. x=4

Then, f(x) =x-3

Let substitute x=4

f(4)=4-3

f(4)=1

4. x=5

Then, f(x) =x-3

Let substitute x=5

f(5)=5-3

f(5)=2

5. x=8

Then, f(x) =x-3

Let substitute x=8

f(8)=8-3

f(8)=5

f(x)=x-3

x. 1 2 4 5 8

f(x). -2 -1 1 2 5

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
