$= -\frac{1}{3}$

Step-by-step explanation:

Given:

$f(x) = \frac{4x - 6}{x}$

Required:

Average range of change over [-3, 6]

SOLUTION:

Find f(-3) and f(6):

To find f(-3), replace x with -3 in the given function

$f(-3) = \frac{4(-3) - 6}{-3}$

$f(-3) = \frac{-12 - 6}{-3}$

$f(-3) = \frac{-18}{-3}$

f(-3) = 6

To find f(6), replace x with 6 in the given function

$f(6) = \frac{4(6) - 6}{6}$

$f(6) = \frac{24 - 6}{6}$

$f(6) = \frac{18}{6}$

f(6) = 3

Average rate of change = $\frac{f(b) - f(a)}{b - a}$

Where,

a = -3, f(a) = 6

b = 6, f(b) = 3

Plug in the values into the formula for average rate of change.

$= \frac{3 - 6}{6 -(-3)}$

$= \frac{-3}{9}$

$= \frac{-1}{3}$

Average rate of change $= -\frac{1}{3}$
