She would place it before the 4.
The -3 in f(-3) is the X coordinate, so you need to find where the line is on the Y coordinate at that point.
The line is at Y = -9
First find the lowest common multiple of the denominators which are 12 3 9 and 27 these all go into 108. Next divide 108 by the original denominators for example 108/12 is 9 then times 9 by the numerator which is 5 and you get 45 so the first one is 45/108. Do this for them all and order by the size of the numerator
The answer would be $2.47
The second table does not represent a function
