A naïve solution for the above-stated problem is to evaluate all of the possible combinations of different pieces of varying size to find the maximum revenue-generating combination. Although this method seems the easiest and quick to practice, it has exponential time complexity. So there is a need to figure out a better method than this.

Question

Determine whether the following systems are linear and time-invariant.
(a) y₁(t) = x(1²)
(b) y2(t) = x(2t) - 1
(c) ya(t) = r(t)- 2x(t - 2)
(d) y₁(t) = x(-t)
(e) ys(t) = x(t) - x(t-10)
