The table shows the outputs y for different inputs x:

Input
(x)
2 4 6 8

Output
(y)
1 2 3 4

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) = 3x – 10. Which relation has a greater value when x = 8?
Part C: Using the relation in Part B, what is the value of x if f(x) = 80?
