Question

The number $N$ (in millions) of US cellular phone subscribers is shown in the table. (Midyear estimates are given.) $$\begin{array}{|c|c|c|c|c|c|c|}\hline t & 1996 & 1998 & 2000 & 2002 & 2004 & 2006 \\ \hline N & 44 & 69 & 109 & 141 & 182 & 233 \\\hline\end{array}$$ (a) Use the data to sketch a rough graph of $N$ as a function of $t.$ (b) Use your graph to estimate the number of cell-phone subscribers at midyear in 2001 and 2005.
