============
Here is one way:
First the lists:
In[18]:= x = Table[i, {i, 1, 3}]
Out[18]= {1,2,3}
In[19]:= y=Table[j, {j, 4,6}]
Out[19]= {4,5,6}
Then the passing the lists to the function. f is left undefined to show the passing of the variables.
In[20]:= Table[f[x[[i]], y[[i]]], {i, 1, Length[x]}]
Out[20]= {f[1,4],f[2,5],f[3,6]}
