Question 1128921


{{{ f(x)=0.3(2.6)^x}}}

Here's an exponential growth function:

{{{y = a(1 + b)^x}}}

{{{y}}}: Final amount remaining over a period of time
{{{a}}}: The original amount
{{{x}}}: Time
The growth factor is {{{(1 + b)}}}.

The variable, {{{b}}}, is percent change in decimal form.

in your case the growth factor is {{{1 + b=2.6}}}=>{{{ b=2.6-1}}}=>{{{b=1.6}}} the function's percent rate of change in decimal form
