x(t)= 10e^-3tu()

Plot the continuous-time signal over the range -1≤t≤5

Break up the time range into two ranges t1=[-1 0] and t2=[0:.1:5]. Then concatenate the results, i.e. t=[t1 t2].

My answer was:

t= 0:.3:-1;

x= exp(-3*t).*u(t)

plot (t,x)

axis (-1 0 -3)

Can't plot the function because of issues.

Please help.
