Question 64926
I am also having a problem with this one 

f(-4) for f (x) =x^3-x^2+x+1 use I have to use the remainder theorem 
can someone please help.....
F(-4) = REMAINDER OBTAINED WHEN F(X) IS DIVIDED WITH X+4....HENCE.....
-4|1-1+1+1
...0-4+20-84
-------------------
...1-5+21-83
HENCE REMAINDER = -83
BY DIRECT SUBSTITUTION WE IND 
F(-4) = -64-16-4+1 = -83
