If X is equal to -1 and the algebraic expression axcubic+bx+1 has the value 6, then if x=1, then you can find axcubic+bx+1.

If X is equal to -1 and the algebraic expression axcubic+bx+1 has the value 6, then if x=1, then you can find axcubic+bx+1.

When X is equal to -1, the value of the algebraic expression axcubic+bx+1 is 6, i.e.-a-b=5, i.e. a+b=-5
When x=1, ax3+bx+1=a+b+1=-5+1=-4

When x=1, the value of algebraic expression ax3+bx+1 is 5, and when x=1, the value of algebraic expression ax3+bx+1 is equal to () A.0 B.-3 C.-4 D.-5

A+b+1=5 when x =1,
Solve to a+b=4,
When x=-1, ax3+bx+1=-a-b+1=-4+1=-3.
Therefore, B.

A+b+1=5 when x =1,
Solution a+b=4,
When x=-1, ax3+bx+1=-a-b+1=-4+1=-3.
Therefore, B.
