A system may or may not be:

1.) Memoryless

2.) Time Invariant

3.) Linear

4.) Casual

5.) Stable

Determine which of these properties hold and which do not hold for each of the following continuous-time systems. Justify your answers. In each example, y(t) denotes the system output and x(t) is the system input.

I don't understand why can assume x(t)=1 for all t and still let input x2(t)=-1

Maybe the answer is linear???

0 r(t)
