question 186

Multiple Choice

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

• A) \(f ( x ) = 10 x ^ { 3 } - 18 x ^ { 2 } - 13 x + 6\)
• B) \(f ( x ) = - 8 x ^ { 3 } + 12 x ^ { 2 } + 5 x - 6\)
• C) \(f ( x ) = - \frac { 10 } { 3 } x ^ { 3 } + 6 x ^ { 2 } + \frac { 13 } { 3 } x - 2\)
• D) \(f ( x ) = \frac { 8 } { 3 } x ^ { 3 } + 4 x ^ { 2 } + \frac { 5 } { 3 } x - 2\)
