Question 19

Multiple Choice

Use a system of equations to find the cubic function f(x) =ax3+bx2+cx+df ( x ) = a x ^ { 3 } + b x ^ { 2 } + c x + d that satisfies given equations. Solve the system using matrices.
f(2) =26f(2) =6f(1) =0f(1) =2\begin{aligned}f ( 2 ) & = - 26 \\f ( - 2 ) & = 6 \\f ( 1 ) & = 0 \\f ( - 1 ) & = - 2\end{aligned}


A) a=2,b=2,c=1,d=1a = 2 , b = - 2 , c = 1 , \quad d = - 1
B) a=26,b=6,c=0,d=2a = - 26 , b = 6 , c = 0 , d = - 2
C) a=3,b=3,c=4,d=2a = - 3 , b = - 3 , c = 4 , d = 2
D) a=26,b=30,c=12,d=16a = - 26 , b = 30 , c = - 12 , d = 16
E) a=50,598,b=54,650c=730,d=518a = 50,598 , b = - 54,650 c = - 730 , d = 518
