help please
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.
Part B: Compare the data in the table with the relation f(x) = 2x + 13. Which relation has a greater value when x = 7?
Part C: Using the relation in Part B, what is the value of x if f(x) = 75?

Best ResponseYou've already chosen the best response.2if each x, maps to only one y value, it can be a function

Best ResponseYou've already chosen the best response.2eg Input (x) 1 1 2 3 Output (y) 2 5 8 11 is not a function, because x = 1, gives two y values: 2 and 5

Best ResponseYou've already chosen the best response.2now what is f(x) = 2x + 13. when x = 7 ie f(7) = 2(7) + 13. = =

Best ResponseYou've already chosen the best response.2when x= 7: y = 8 and f = 27 which is greater
