12The remainder R when fx 20x30 4x3 23x 2 is divided by x1
12.The remainder R when f(x) - 20x30- 4x3 + 2-3x +2 is divided by x+1 is 13. If f(x) 1+1 and g(x) x+1, find (f) (x). Also find the domain
Solution
12.f(x)= 20x30-4x3+x2-3x+2
f(-1)= 20(-1)30-4(-1)3+(-1)2-3(-1)+2
= 20+4+1+3+2=30
So the remainder is 30.
