The polynomial function of lowest degree with lead coefficient 1 and roots 1 and 1 + i is f(x) = x3 - 3x2 + 4x - 2.
Answer:
- The measure of reference angle is
. 
Step-by-step explanation:
Converting 
to degrees,
This means lies in Quadrant 4, and thus its reference angle is 
Since lies in the fourth quadrant, 
and 
are negative.
Since lies in the fourth quadrant, 
is positive, and is equal to 
Hello,
y=x²-x-2=x²-2*1/2*x+1/4-2-1/4=(x-1/2)²-9/4
1. Vertex=(1/2,-9/4)
2. if x=0 then y=0²-0-2=-2
3.The roots:
x²-x-2=0
==>(x-1/2)²-9/4=0
==>(x-1/2-3/2)(x-1/2+3/2)=0
==>(x-2)(x+1)=0
x=2 or x=-1
4. axe of symmetry: x=1/2
