I tried the smooth(), but it did not hep.

clc;
clear all;
close all;
t=0:20;
V_1=1 - ((1.10625)*(exp(-0.438*t))) + ((0.10625)*(exp(-4.56*t)));
V_2=1+((exp(-0.5*t)).*((-0.9)*(cos(1.323*t))-(0.34)*(sin(1.323*t))));
%V1=smooth(V_2);
plot(t,V_1,'r')
hold on
plot (t,V_2,'b')
legend('OverDamped','UnderDamped')
Thank you in advance.

t=linspace(0,20,100);

You get sharp plots when you sample a curve far apart compared to how rapidly it is changing. You were sampling only at the integers 0, 1, 2, 3, and so on, which is only 4 3/4 points per cyle of your sin() and cos() of 1.323*t
