Question

How do i graph the polynomial function:f(x) = -x^(3)  - 2

anonymous · Answer

Find three sets that solve the equation

mertsj · Answer

Find the basic shape of a cubic.  Move it down two units and reflect it about the x axis since the coefficient of the x^3 term is negative.

anonymous · Answer

Could one of you do a step by step for me?

anonymous · Answer

I'm having hard time remembering but I'll see what I can do, first replace the x with a  number lets say 1 so the equation would look like this f(x)=-1^(3)-2..... f(x)=-1-2.......f(x)=3, so the set is (1,3), keep doing this till you get three sets then check.

P.S. To those who might answer after me if I did something wrong tell me.

so i can pick any number to use?

anonymous · Answer

from what I remember yes just make sure you don't screw up when you solve the equation that could throw you off.

anonymous · Answer

give me an example and I'll see if your doing it right

anonymous · Answer

f(x)=-2^(3)-2
=-8-2
=-10
(2,-10)
