Hint for 2.9:

An __**incrementally linear system**__ can be expressed as a combination of a linear
system and an adder that adds an offset y<sub>zi</sub>(t) to the output of the linear system. The value of offset y<sub>zi</sub>(t) is the zero-input response of the original system.
System S1, y(t) = 3x(t) + 5, for example, can be expressed as a combination of
a linear system S2, y(t) = 3x(t), plus an offset given by the zero-input response
of S1, which equals y<sub>zi</sub>(t) = 5.
