Domain Functions:(adsbygoogle = window.adsbygoogle || []).push({});

f(x) = 4sq.root(1-x2), the 4 is on the outside

f(s) = sq.root(s -1)/s-4

f(x) = x-4/sq.root x

I have absolutely no clue how to go about doing any of these, I take notes but I cannot piece it together; I have never felt so helpless at anything. This isn't homework I just want to know how to be able to do slope-intercept, determine a function, evaluate it, domain functions and difference quotients becaue I have a quiz on it tomorrow at 8:30 and I need to know how to at least start to solve them.
