Question 1196548
.
<pre>

The average rate of change of a function f(x) as x changes from "a" to "b" on the number line, is the ratio

    average rate of change = {{{(f(b) - f(a))/(b-a)}}}.


Step by step, it means that you calculate


(a)  f(a);


(b)  f(b);


(c)  the difference f(b)-f(a)     <<<--===  in this order (!)


(d)  the difference  (b-a)        <<<---=== in this order (!)


(e)  then divide the difference  f(b)-f(a)  by the difference  (b-a).
