How would I plot the addition of the following continuous time signal; should I determine a function as x1(t) and then plot the addition of the 2 functions?

x1(t) = {2 -3<t<0 (this is the piecemeal function)

{t/3 0<t<3

{0 otherwise

using t = -10:0.01:10 plot the following in a figure

x1(t+1) &

x1[(t/2)-1]

@Andre, instead of flagging your question as unclear, you could also edit your question to make it more clear.

Ah ok; I fixed it up, also fixed some of the number I mistakingly put. I feel bad as someone has already answered.

x1 = @(t) (-3 < t & t < 0).*(-1) + (0 < t & t < 3).*t/3;
t = -10:0.01:10;
y1 = x1(3*t+1);
y2 = x1(-t/2-1);
figure();
axes();
hold on
plot(t, y1)
plot(t, y2)
legend({'y1', 'y2'});
