The table shows the outputs, y, for different inputs, x: input (x) 1 2 3 4 output (y) 5 5 7 9 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 − 8. which relation has a greater value when x = 4? (2 points) part c: using the relation in part b, what is the value of x if f(x) = 34? (5 points)

A. yes, this is a function because there is no repeating x values. There can be repeating y values, just not the x ones. <==

B. Table :
u already have the output when x = 4(4,9)the output(y) = 9

   relation :
   f(x) = 2x - 8when x = 4
   f(4) = 2(4) - 8
   f(4) = 8 - 8
   f(4) = 0

the table has the greater value. <==

C. f(x) = 2x - 8...when f(x) = 34
    34 = 2x - 8
    34 + 8 = 2x
    42 = 2x
     42/2 = x
    21 = x <==
