Question

This table shows the input and output values for a linear function f(x). What is the difference of outputs for any two inputs that are one value apart? −30 −25 1 20

Answer 1

Is there a -25?

Explanation:

if so i did the test

Answer 2

-25.

Explanation:

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:

Output 3 - Output 2:

Output 4 - Output 3:

Output 5 - Output 4:

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