The table gives the number of active Twitter users worldwide, semiannually from 2010 to 2016.

Step 1 Using Desmos, first add a table. (click on "+" at the upper left) and add the numbers. It should look something like in this image:

$\begin{array}{|cc|}\hline x_1& y_1\\ 0& 30\\ 0.5& 49\\ 1& 68\\ 1.5& 101\\ 2& 138\\ 2.5& 167\\ 3& 204\\ 3.5& 232\\ 4& 255\\ 4.5& 284\\ 5& 302\\ 5.5& 307\\ 6& 310\\ 6.5& 317\\ \hline\end{array}$

Step 2 Next, you can get the exponential model form $y=a\cdot e^{kx}$ by typing in the next box below the one with the table: $y_1\to a\cdot e^{k{x}_1}$ Using the output from Desmos, we can write the exponential model as follows: $y=89.1544\cdot e^{0.219711x}$
$y_1\sim a{b}^{x_1}$
$R^2=0.8627$ $e_1$
$a=89.1544$
$b=1.24572$

Step 3 You can get the logistic model form $y=\frac{M}{1+A{e}^{-kx}}$ by typing: $\text{Undefined control sequence rightarrowM}$ Using the output from Desmos, we can write the logistic model as follows: $y=\frac{325.764}{1+8.75376\cdot e^{-0.892708z}}$
$y\sim \frac{M}{1+A{e}^{-k{x}_1}}$
$R^2=0.9988$
$e_1$
$m=325.764$
$A=8.75376$
$k=0.892708$

Step 4 The logistic model is more accurate because it has larger $R^2$ value. You can also see this from the graph below: The exponential and the logistic models are represented by the red and blue color curves respectively.
