PLEASEEE HELPP!!!!!

The table shows the outputs y for different inputs x:

Input
(x) 3 7 11 15
Output
(y) 4 6 8 10

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 – 21. Which relation has a greater value when x = 11?
Part C: Using the relation in Part B, what is the value of x if f(x) = 99?

`Part A: Do the data in this table represent a function? Justify your answer.`

are there any repeated x values in row 1? if yes, then you do NOT have a function. A function has any given x value match to exactly one y value. You can't have x = 1 paired with y = 1 and y = 2 at the same time.
