Alright, I did a few more questions and came back to this one and found the answer. I thought I'd post it incase anyone ever runs into this problem.
a) y= f(x)
y= 1 ...... I just found the function where X=4 and the answer for y is 1
b) I just took the value for x from the chart and found the value that went with it for f(x)... since f(x) = y
c) I found the point where f(4) was and noted what the y value was
I guess it was a pretty simple question that I made complicated in my head before I did it. It really helps to skip ahead to the next question sometimes...
