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?

Answer 1

Answer:

-25

Step-by-step explanation:

The "x" values in the table are INPUT

and

The "y" values in the table are OUTPUT

We see that each of the values in INPUT (x) are 1 values apart, so we can look at the difference (later - previous) for any 2 x values:

-5 - 20 = -25

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

and so on..

Hence, the difference is "-25"

2nd answer choice is right.
