The table shows the outputs y for different inputs x:
Input
(x) 5 6 7 8
Output
(y) 2 5 8 11
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) = 2x + 13. Which relation has a greater value when x = 7? (2 points)
Part C: Using the relation in Part B, what is the value of x if f(x) = 75? (5 points)

Best ResponseYou've already chosen the best response.0The column corresponding to x =7 in the table, is here  Input  (x) 5 6 [7] 8 Output (y) 2 5 [8] 11   The value of the function: f(x) = 2x + 13 , evaluated at x=7 is f(7) = 2(7) + 13 =
