Find all real and non-real roots of the function ƒ(x) = (x2 + 4)(x – 2). Question 10 options:

A)

x = ±2i, 2

B)

x = ±2i

C)

x = ±4i, 2

D)

x = ±2

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
