Question

Examine the wintegraph of monear function

Answer 1

Answer:

$Rate = 3$

Step-by-step explanation:

Given

The attached graph

Required

Average rate of change over $1 \le x \le 3$

This is calculated as:

$Rate = \frac{f(b) - f(a)}{b - a}$

$[a,b] = [1,3]$

$[f(a),f(b)] = [-2.4]$

So, we have:

$Rate = \frac{4 - (-2)}{3 - 1}$

$Rate = \frac{6}{2}$

$Rate = 3$
