Hello, I am new to MATLAB. I have a piecewise function as follows.
How do I plot the graph of such a function? Any help would be appreciated, thank you!

Using the Symbolic Math Toolbox (if you have it):
syms t
a=1;
f=piecewise(0<t & t<a, exp(t), t>=a, 2*exp(t));
fplot(f,[0,2*a])

One possibility:
a=1;
f=@(t) exp(t).*(0<t & t<a) + 2*exp(t).*(a<=t);
fplot(f,[0,2*a])
