Solve the problem.The value of a certain baseball card is modeled by 
where V(t) is the value in dollars t years after the baseball card was printed. Find the second approximating polynomial, P2(t), centered at 
, and use it to predict the value of the card 53 years after it came out.
A. P2(t) = 4475.7568 + 4475.7568(t - 48) + 559.4696(t - 48)2 P2(53) = $15,665.15 B. P2(t) = 4475.7568 + 1118.9392(t - 48) + 139.8674(t - 48)2 P2(53) = $7273.10 C. P2(t) = 17,903.027 + 4475.7568(t - 48) + 559.4696(t - 48)2; P2(53) = $54,268.55 D. P2(t) = 17,903.027 + 4475.7568(t - 48) + 1118.9392(t - 48)2 P2(53) = $31,330.30
