Which is a correct expansion of (4x + 1)(2x^2 - 2)?

Hello :)

They are basically asking which one of these expansion would give you the right answer.

So first you would have to solve the expression, by using foil.

(4x+1)(2x^2-2)

F- first

4x · 2x^2

O- outer

+4x · (-2)

I- inner

+1 · 2x^2

L- last

Put all of the expressions together.

the answer would be A

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2
