Piecewise f(x) function diagram


In a series of Aluminum cutting experiments,
Jimmy summarizes the relationship between the force and the heat
conducted to the cutter. He finds that the heat is a piecewise function
of the force. In order to amylases the property of the cutter, he wants
to analysis the
heat released to the cutter at jump points. The unit for the force is
kN, and the unit for the heat is J.
