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)

Respuesta :

Part A: No it is not a function, there is no corresponding proportional relationship between the input and output

Part B: f(x) = 2x + 13 has the higher value when x=7

Part C: x=31
