# Plotting solutions to Solve results

I am trying to plot a solution to a Solve result, ie I have a function f(x,y) and I want to plot y=y(x) for when f(x,y) = 0.06366. Here is what I am trying to do

f[x_, y_] := 0.5*Erf[(y - 0.04*x^2)/(0.1*Sqrt[x])] + 0.5;
Plot[Evaluate@Table[Solve[f[x, y] == 0.06366, {x, y}, {y, Range[0, 1, 0.2]}],
{x, 0, 7}], PlotRange -> Full]

Why not directly plot the expression in terms of InverseErf[] that you get from Solve[]? –  Guess who it is. May 27 '13 at 7:17
I want to be able to do this for a general f(x,y) –  l3win May 27 '13 at 7:26

f[x_, y_] := 0.5*Erf[(y - 0.04*x^2)/(0.1*Sqrt[x])] + 0.5;
