Some of your parentheses are incorrect: [] is for functions, () is for
grouping, {} is for lists. Other than that, I guess you should write f[x]
instead of just f in your Plot command:
In[1]:=
Clear[a, b, f];
f[x_] := 1 - Cos[E^((3*x)/4)];
{a, b} = {-1, 1.5};
c = Plot[f[x], {x, a, b}];
works all right.
