Question

Given the following table, find the rate of change between 1-4) and 10).

х
-4 -2 0 2 4
f) -2 -1 0 1 2

Answer 1

• 1/2

Explanation:

As per given table there are pairs:

• (-4, -2), (-2, -1), (0, 0), (2, 1), (4, 2)

This is line passing through the origin and the equation is:

• f(x) = 1/2x

Rate of change is the slope 1/2, which is same over any interval
