Question
hand written plzz The table shows the number of phones sold by a small cell phone provider in various years. Use a calculator to write a quartic model for the number of phones sold in a given year since 1996 and use the model to estimate the number of phones sold in 2005. Year 1998 1999 2002 2003 2004 2006 Number of 131 148 175 Cell Phones 223 282 364 P(x) = -0.44x4 + 10.10x³ - 75.75x2 + 232.11x - 103.94 The estimated number of phones sold in 2005 is 316. P(x) = -0.25x³ + 8.48x2 - 42.28x + 191.29 The estimated number of phones sold in 2005 is 339. P(x) = -0.44x+10.10x³ - 75.75x² + 232.11x - 103.94 The estimated number of phones sold in 2005 is 339. P(x) = 0.25x³-8.48x² + 42.28x - 191.29 The estimated number of phones sold in 2005 is 316.
