how to find partition function text applied to a table

Hi,

I recently took over a database that has a partition_scheme and partition function applied to a table. When I look at the table and it's indexes I cannot find where (on what column) the function is being applied. In addittion I cannot find the text of the partition function (it's defintion).  I tried sp_help which indicated that the index is located on the <Function name>.  I tried right clicking on the table and all its indexes and selecting create to but I am not seeing the on clause at the end of the create statement. There must be a view/table that containts this information.

thanks
