does anyone know a website which shows the 8 types of parents graphs that show their properties( domain, range, assymptotes, minimum or maximum)?

Eight types of functions are graphed and explained at this tutorial site:

There is a place to click on the page to get it to work interactively.

I don't know what you mean by Parents graphs.
