Is the following what you want?
In[1]:= f[x_, tau_:1] := tau*Exp[-x] In[2]:= g[x_, mu_:1] := mu*x^2
In[3]:= Plot[f[g[x]], {x, 0, 1}];
or do you mean Convolution in the Fourier sense?
I took the liberty of declaring tau and mu with default values (rather
than using a global assignment or a substitution rule).
Cheers,
Paul
