a continuous time signal shown in the  fig.determine the following version of  the signal  a)x(t+2)    b)−(x)t     c)x(3−2t)     d)((x(t)+x(−t))/2)
$${a}\:{continuous}\:{time}\:{signal}\:{shown}\:{in}\:{the} \\ $$$${fig}.{determine}\:{the}\:{following}\:{version}\:{of} \\ $$$${the}\:{signal} \\ $$$$\left.{a}\right){x}\left({t}+\mathrm{2}\right)\:\: \\ $$$$\left.{b}\right)−\left({x}\right){t}\:\: \\ $$$$\left.\:{c}\right){x}\left(\mathrm{3}−\mathrm{2}{t}\right)\:\:\: \\ $$$$\left.{d}\right)\frac{{x}\left({t}\right)+{x}\left(−{t}\right)}{\mathrm{2}} \\ $$

A "continuous" time signal in the popular meaning I guess, because that x(t) for t=1 is not continuous in the mathematical meaning

thank you sir for your comment  in communication signals   countinuous time signals  means the value of (t) is countinue   in x(t) not discrete points so countiue  time signals need not to be countinuoues  mathmaticaly

for example a is countinuous time signal  and b is discrete time signal
