If f(-2)=16 which could be the equation for f(x) a. f(x)=x-18 b. f(x)=20-2x c. f(x)=3x+24 d. f(x)=8-4x

The answer is D

Let x = -2

f(-2) = 8 - 4(-2)

f(-2) = 8 + 8

f(-2) = 16

D is the answer.

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.

the correct answer is 5 6 and 7
