The table shows the outputs, y, for different inputs, x:

input (x) 2 5 9 12
output (y) 20 15 12 8

part a: do the data in this table represent a function? justify your answer.

part b: compare the data in the table with the relation f(x) = 5x + 14. which relation has a greater value when x = 9?

part c: using the relation in part b, what is the value of x if f(x) = 64?

You drop a rubber ball off the roof of a 50 meter high building onto a paved parking lot. it bounces back up with every bounce, but not quite all the way back up to you. after the first bounce it bounces back only 80 percent of the distance it was dropped from. the pattern continues, meaning after every bounce it comes up to just 80 percent of the previous maximum height. so if before the first bounce the height is 50 meters, what height does the ball reach after the fifth bounce? round your answer to one decimal place and chose the correct response from the choices below:
