A. Â Â The data in the table represent a function. y=x/2. This is seen as for every value of x in the table, y=x/2(half of it). You can show this further by trying this fact on each value.
B. Â For the original function, when x =8, y=x/2=4
For the function given in this part, when x=8, y=3(8)-10
                                 y=24-10                                                       y=14
   This means the relation given in this part has a greater value when x=8
C. When x=80, f(x)=3(80)-10
              =240-10
              =230Â
