Does this graph represent a function? Why or why not? A. No, because it fails the vertical line test.
B. Yes, because it has two straight lines.
C. No, because it is not a curve.
D. Yes, because it passes the vertical line test.

A

Step-by-step explanation:

it fails the vertical line test which is a test to see if a graph is a function

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 number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.
