Question 23

Multiple Choice

Solve the problem using matrices.
-Find the function f(x) =ax3+bx2+cx+df ( x ) = a x ^ { 3 } + b x ^ { 2 } + c x + d for which f(0) =2,f(1) =5,f(1) =3f ( 0 ) = - 2 , f ( 1 ) = 5 , f ( - 1 ) = 3 , f(2) =4f ( 2 ) = 4 .


A) f(x) =10x318x213x+6f ( x ) = 10 x ^ { 3 } - 18 x ^ { 2 } - 13 x + 6

B) f(x) =8x3+12x2+5x6f ( x ) = - 8 x ^ { 3 } + 12 x ^ { 2 } + 5 x - 6

C) f(x) =103x3+6x2+133x2f ( x ) = - \frac { 10 } { 3 } x ^ { 3 } + 6 x ^ { 2 } + \frac { 13 } { 3 } x - 2

D) f(x) =83x3+4x2+53x2f ( x ) = \frac { 8 } { 3 } x ^ { 3 } + 4 x ^ { 2 } + \frac { 5 } { 3 } x - 2
