Multiple Choice

Solve.
-A biking club has increased its membership each year since its founding in 1984. The table provides membership data for several years. $$\begin{array} { c | c } \text { Year } & \text { \# of Members } \\\hline 0 & 7 \\5 & 12 \\10 & 16 \\12 & 19 \\14 & 20\end{array}$$ Determine the linear, quadratic, cubic, or quartic function that best fits the data.

• A) \(f ( x ) = 0.003 x ^ { 4 } - 0.98 x ^ { 2 } + 7.03 x + 1.57\)
• B) \(f ( x ) = - 0.003 x ^ { 2 } + 0.98 x + 7.03\)
• C) \(f ( x ) = 0.94 x + 7.08\)
• D) \(f ( x ) = 0.0002 x ^ { 3 } - 0.006 x ^ { 2 } + 0.99 x + 7.03\)
