 Dear Mathematica Experts,I have a question regarding the Minimize function. f[x,y]:= 3x^2+y+2; I need to find the Minimum of x only, and I have condition f[x,y]=3.84, I used the following script, but it is not working, fMinimize[{f[x,y],f[x,y]==3.84},x],what will be the correct script to do the same? I am looking forward to hearing from you.Best.Melbin
 Try: NMinimize[{ch[a1, x], 10^(-11) < x < 20000}, a1]
