How to plot basic signal

So I am trying to plot basic signals in MATLAB for an assignment, and I am wondering how to do so. For example how would I plot a signal such as "plot x1(t)=u(t+1)-u(t-5) where -7 < t < 7seconds"

Good that you admit it is an assignment question. That's why can you first please show whatever code you have tried to attempt? Then, it is ok for people to correct your code to guide you.

I have tried using heaveside and fplot from another person that asked a similar question, I used this.

syms t l
l(t) = heaviside(t+1) + heaviside(t-5)
fplot(l, [-7,7])

But I believe that I am doing the first part of the question, but not the "where -7 < t < 7seconds" part

After your code, try limiting the x axis to -7 to 7

xlim([-7, 7]);

Or you can use a numerical example - not syms. Like

numElements = 1000;
t = linspace(-7, 7, numElements);
% Compute l(t) then plot  % You can do this line yourself.
plot(t, l, 'LineWidth', 2);
xlabel('t')
ylabel('l(t)');
grid on;
