Applying my function to elements of a vector

Hello everyone,

Say I've created a function, f[x_], which accepts a single scalar as 
its argument.  I now want to apply that function to each element of a 
vector, v, of length n, as in

	newVector = f[v],

but I get an error because my function f does not thread over the 
elements of the vector as do built-in Mathematica functions such as 
Log[].  How can I get my function to apply to each element of my 
vector?

	Regards,

		Greg
