I suggest you take some time to read some introduction to Mathematica. 

In[1]:=
alist = {1, 1.5, 7, 4, 3, 2001};
In[2]:=
Map[f, alist]
Out[2]=
{f[1], f[1.5], f[7], f[4], f[3], f[2001]}

Or, if you wish, you may use the prefix notation:

In[3]:=
f /@ alist
Out[3]=
{f[1], f[1.5], f[7], f[4], f[3], f[2001]}
