(BIC 設 deg f(x)≥4,若f(x)除以(x-1)餘式為3x+2,除以(x+2)餘式為5x-3,請選出正確的選項。
D
(A)x-1除f(x) 餘式為5
(C)(x-1)(x+2)除f(x)餘式為6x-1
4-5-6
(B)x+2除f(x)餘式為-13
(x-174(x+2)+0xbxte
a+b+c=5, 42-2b+c=13
(D)(x-1)2(x+2)除f(x) 餘式為-x2+5x+130-35--18.
(E) (x-1)² (x+2)² f(x) (x²+5x+1 = (x-179 +3x+2 +11x=5 = (x-1)x+2) of torty
f(x)=
5-2015=13
4654
+(x+2)+5x-3 11-27--13 +-513 3α=18
☆02. 已知a、b、c均為實數,若二次函數f(x)=ax²+bx+c滿足f(7)=f(-7)、f(3)<0、f(5)>0,請選出正確的
