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. (3 points)
Part B: Compare the data in the table with the relation f(x) = 5x – 21. Which relation has a greater value when x = 11? (2 points)
Part C: Using the relation in Part B, what is the value of x if f(x) = 99? (5 points)

Best ResponseYou've already chosen the best response.0for A, functions don't repeat xvalues. So if all the x's are different it's a function.

Best ResponseYou've already chosen the best response.0for B, you need to find f(11) to make the comparison. Plug in 11 for x and simplify. \[f(11) = 5(11)21\]
