The table shows the outputs y for different inputs x:
Input
(x) 2 4 6 8
Output
(y) 1 2 3 4
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) = 3x – 10. Which relation has a greater value when x = 8? (2 points)
Part C: Using the relation in Part B, what is the value of x if f(x) = 80? (5 points)

Best ResponseYou've already chosen the best response.2PART A) every x values goes t0 ONLY one y value A function is when x values does not repeat , if there is same x value more than onc than relation is a not function PART B) substitute x value and then solve for f(x) in the table when x = 8 y =what ? for example when x=6 y =3 PART C) substitute 80 for f(x) and then solve for x
