F(n)=2n+3
Find f(-10)

Greetings from Brasil...

Just replace the N of the function F(N) with the requested value - 10:

F(N) = 2N + 3

F(- 10) = 2 · (- 10) + 3    now N has been replaced by - 10

F(- 10) = - 20 + 3

y=x+2 hope this jdjxhdnzbdjdo

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.
