+class Function(object):
+	r"""Wrapper around function specifying the domain
+
+	Provided a function :math:`f: \mathcal{D} \subset \mathbb{R}^m \to \mathbb{R}^d`,
+	and a domain :math:`\mathcal{D}`, this class acts as a wrapper for both.
+	The key contribution of this class is to provide access to 
+	the function on the *normalized domain* :math:`\mathcal{D}_{\text{norm}}` 
+	that is a subset of the :math:`[-1,1]^m` cube; i.e.,
+
+	.. math::
+
+		\mathcal{D}_{\text{norm}} \subset [-1,1]^m \subset \mathbb{R}^m.
+ 
+
+
+	Parameters
+	----------
+	fun: function or list of functions
+		Either a python function or a list of functions to evaluate
+	domain: Domain
+		The domain on which the function is posed	
+	vectorized: bool, default: False
+		If True, the functions are vectorized for use with numpy.
+	fun_kwargs: dict, default: empty
+		Keyword arguments to pass to the functions when evaluating function
