Even part of signal X(t)
Odd part of signal X(t)
In que 2 the equation of the graph is given. Thus X(-t) is found by substituting -t in place of t .
If X(t)= X(-t) then it is an even signal thus it doesn't have any odd part.
If X(t) =X(-t) then it is an odd signal thus it doesn't have any even part.
If a signal doesn't satisfy any of the above condition then it is NEITHER ODD NEITHER EVEN signal . Such signals have both even and odd parts.
You can verify above points.
Please consider the labeling as X(t) on y-axis of continuous time signals and X[n] on y-axis of all descrete time signals and t on x-axis of all graphs.
I have answered all your questions.
Please rate a thumbs up if satisfied.
Have a nice time ahead :)
