syms y(x)
y(x) = piecewise(-0.5<x<0,(2+4*x),0<=x<+0.5,(2-4*x), 0);
figure; %tmin=-6;tmax=6;N=100; want these limits -6<=x<=6
fplot(y);

clear; clc;
syms t g(x) x(t)
g(t) = piecewise(-0.5<t<0,(2+4*t),0<=t<+0.5,(2-4*t), 0)
x(t)=sym(0);
for k=-6:1:6
x(t)=x(t)+g(t-k);
end
subplot(2,1,1); fplot(g, [-6 6 ]);
grid on; zoom on; ylim([-0.1 2.1])
xlabel('t'); ylabel('g(t)'); title('one period')
subplot(2,1,2); fplot(x, [-6 6 ]);
grid on; zoom on; ylim([-0.1 2.1])
xlabel('t'); ylabel('x(t)'); title('signal x(t)')
...and if you run it:

@Dimitris Kalogiros so i have to plot the fourier coefficinets for -101<= k<= +101 for the evaluation of the fourier series can we do it on the same graph with changing the above k limits for new limits or do we have to define a new k value for -t<= t <= 1 ??

This is my last contribution...
Keep in mind that for your example fourier coefficients are, after all, real numbers and are not zero for add index or 0.
