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!
