I just got Mathematica last night and am trying to use it for the first time. I'm trying to plot a graph [tex] f(x)=K(1-x)^{\frac{-3}{8}} [/tex] but it's not working right. I tried first with K = 325 (for physical reasons) and the graph started negative at x=0. If I choose K to be almost anything other than 325 the graph starts at 0 which is also wrong. The command I gave was Plot[325(1-x)^(-3/8), {x,0,0.9}]. Did I do something wrong?(adsbygoogle = window.adsbygoogle || []).push({});
