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

input (x) 6 12 15 25
output (y) 14 15 15 16

part a: do the data in this table represent a function? justify your answer. (3 points)

part b: compare the data in the table with the relation f(x) = 7x − 15. which relation has a greater value when x = 6? (2 points)

part c: using the relation in part b, what is the value of x if f(x) = 6? (5 points)
