Find the inverse

f^-1 (x) = 2x - 5/2

Step-by-step explanation:

First you swap the equation so it's 2x +5/4 = x then multiply both sides by 4 so it's 2y + 5 = 4x then move the constant to the right so it's 2y=4x-5 then you divide the equation by 2 so it's y=2x- 5/2 and substitute f^-1 (x) for y so it turns into f^-1 (x) = 2x - 5/2 Hope this helps I tried my best

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.
