The graph represents the relation the function that coincides with this relation is 1. f(y)=|y|/2 f(y)=2|y|/3 f(y)=|y|/5 f(y)=5|y| 2. f(y) =3y/2 when y us greater than 0 f(x)= -3x/2 when -y is less than or equal to 0 f(x)= -x/5 when y is less than 0 f(y)= 5y when y is less than or equal to 0

a) input mismatch exception

explanation:

the scanner.nextint method throws an unchecked input mismatch exception if a user enters an input that is not an integer.

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.
