## anonymous 3 years ago f(x)=-2x^3-4x^2+3x-8, use the remainder theorem to determain f(-1)

1. hartnn

to get f(-1), just replace 'x' in f(x) by -1

2. anonymous

Can on of you guys help me :D

3. hartnn

ok, i think the question states to use remainder theorem, means you need to divide f(x) by x+1, and the remainder would be f(-1)

4. anonymous

-13?

5. hartnn

yes, thats correct, but make sure you divided f(x) by x+1 to get the remainder as -13

6. anonymous

thank you (:
