10: Since we cannot easily guess the graph of a sum of two known functions, we have to first write the given function in a different way. We need to get rid of one x so that the variable appears only once, completion of square seems the obvious way.

The basic function is g(x) = x². In order to fix its argument one has to do these transformations in the following order.

Apply appropriate transformations to the graph of g in order to obtain h. Then identify transformations applied to value that turn h into f.
