based on the graph above, estimate (to one decimal place) the average rate of change from ( x = 1 ) to ( x = 4 ).
question help: video post to forum

Explanation:

Step1: Identify f(1) and f(4)

From the graph, $f(1) = 6$, $f(4) = 0$

Step2: Apply average rate formula

Average rate of change = $\frac{f(b)-f(a)}{b-a}$, where $a=1$, $b=4$
$\frac{f(4)-f(1)}{4-1} = \frac{0-6}{3}$

Step3: Calculate and round result

$\frac{-6}{3} = -2.0$

Answer:

-2.0
