Hello,
A cubic polynomial with -2,1,2 as roots is
f(x)=k*(x+2)(x+1)*(x-2)=k(x²-4)(x+1)=k(x^3+x²-4x-4)
Looking the answers ==>k=1
==>Answer A
Answer:
its the same thing as saying what is the Y-intercept
Step-by-step explanation:
Your multiplying by -4 each time
-1x-4=4
4x-4=-16
-16x-4=64
That chord is called diameter.
