Answer 2

What is the difference of outputs for any two inputs that are one value apart?

If you look at the column of "x" [input], you will see that they are 1 unit apart. You can thus look at the corresponding values of "f(x)" [output] and determine their difference. Checking all of those, gives us the difference (same for all).

Output 2 - Output 1:

$-5-20=-25$

Output 3 - Output 2:

$-30-(-5)=-30+5=-25$

Output 4 - Output 3:

$-55-(-30)=-55+30=-25$

Output 5 - Output 4:

$-80-(-55)=-80+55=-25$

So the difference of outputs for any two inputs one value apart are $-25$

ANSWER: $-25$
