Question 355

Multiple Choice

Find an nth degree polynomial function with real coefficients satisfying the given conditions.
- n=4;3,12\mathrm { n } = 4 ; 3 , \frac { 1 } { 2 } , and 1+3i1 + 3 \mathrm { i } are zeros; f(1) =54\mathrm { f } ( 1 ) = - 54


A) f(x) =6x433x3+111x2228x+90f ( x ) = 6 x ^ { 4 } - 33 x ^ { 3 } + 111 x ^ { 2 } - 228 x + 90
B) f(x) =2x411x3+37x2228x+90f ( x ) = 2 x ^ { 4 } - 11 x ^ { 3 } + 37 x ^ { 2 } - 228 x + 90
C) f(x) =3x433x3+111x2228x+90f ( x ) = 3 x ^ { 4 } - 33 x ^ { 3 } + 111 x ^ { 2 } - 228 x + 90
D) f(x) =4x4+22x374x2+152x60f ( x ) = - 4 x ^ { 4 } + 22 x ^ { 3 } - 74 x ^ { 2 } + 152 x - 60
