Now, suppose one of the roots of the polynomial function is complex. The roots of the function are
2+i, and 5. Write the equation
for this polynomial
function.
Which of the following must also be a root of the
function?
A. -3
B. -5
C. 2-i
D. 2i

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
