In terms of a general function f(-x) in compared to f(x), the function will always be reflected about the y-axis for any function not just a unit or ramp function.

In terms of those other properties, a good way to check these is to break them up into parts when the ramp starts and when it's zero and just do a piece-wise check. If you have to show these properties mathematically, you just do this symbolically.

So as an example for the step function we know that h(t-a) can be analytic when you split it up at t < a and t >= a (or whatever definition you use). If you have two functions like this you get four partitions and then you just consider all of those individually.
