Hi folks,
we are searching all solutions where the function f results null.
f[x_] := -7500 * Ceiling[(0.5 * x) / 880] + (5 * x)
Solve[{f[x] == 0}, x]
As f contains jump discontinuities, we recieved the following error:
InverseFunction::"ifun": "Inverse functions are being used. Values may be \
lost for multivalued inverses."
Solve::"tdep": "The equations appear to involve the variables to be solved \
for in an essentially non-algebraic way."
We would be pleased if anybody could help us.
Regards,
Philipp Burkert
