What am I doing wrong with this code?

I think I'm having a brain fart. Seriously... Plot[{1/(1 + y^2), (1/y - 1)^(1/2)}, {y, 0, 5}] What is wrong with that code? Maybe it's not solvable in mathematica? I'm trying to plot nullclines of a system of ODEs. and those function up there are them. I just can't get mathematica to plot them in the same graph. I get an error message saying... >From In[22]:= (1/y - 1)^(1/2) is not a machine-size real number at y = 1.0000001666666667`. Any help is appreciated. sean
