Question

The table shows the outputs y for different inputs x:

Answer 1

A. yes...the data is a function because for every x value, there is only one y value.

B. f(x) = 3x - 10...when x = 8
    f(8) = 3(8) - 10
    f(8) = 24 - 10
    f(8) = 14
  
   the table : wen x = 8, y = 4

    f(x) = 3x - 10 has a greater value

C. 80 = 3x - 10
    80 + 10 = 3x
    90 = 3x
    90/3 = x
    30 = x
