#1**+2 **

p(x) is the answer that goes in the top left box

x cannot be > 1 in this function because we would have a negative under the square root

q(x) is the answer that goes in the bottom left box

x cannot be > -1 ...for instance...if x = 0, we get -1 under the root which isn't real

r(x) goes in the top right box

x cannot be < -1 ...we get a negative under the radical

s(x) goes in the bottom right box

If x < 1, we get a negative under the radical

I hope I haven't confused you, RP
