Hello. I obtained an interpolated function from a set of data representing a velocity curve (increasing & decreasing). I used the following vr =Interpolation[data]; Solve[vr[x]==0.6,x] InverseFunction::ifun: Inverse functions are being used. Values may be lost for multivalued inverses. Out[221]={{x->1. InverseFunction[InterpolatingFunction[{{0.,0.95}},<>],1,1][0.6]}} I'm expecting something like x = 3 or x = 9 (two solutions). Any suggestions are highly appreciated! Jasem Mutlaq.
