Determine the growth defined by the equation y=3(3.4)x

jekas [21]

$\bf \qquad \textit{Amount for Exponential Growth}\\\\
A=I(1 + r)^t\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
I=\textit{initial amount}\\
r=rate\to r\%\to \frac{r}{100}\\
t=\textit{elapsed time}\\
\end{cases}\\\\
-------------------------------\\\\
\stackrel{A}{y}=\stackrel{I}{3}(3.4)^{x}\implies y=3(1+\stackrel{r}{2.4})^x
\\\\\\
\cfrac{r}{100}=2.4\implies r=100\cdot 2.4\implies r=\stackrel{\%}{240}$
