	Try FindMinimum.  To get a maximum, try using FindMinimum applied to
the negative of the function.  You will have to specify a starting point.

After consulting several books and online reference I cannot figure out how
to find the maximum and or minimum values of functions.  It seems there must
be a built in command for this type of thing, but I'll be damned if I can
find it.  (yes I can do this on a calculator, but I should be able to do it
in mathematica!)

here is an example:
f(x)=x^2 - 7x -49

Also, is there a built in function that will report the vertex in the form
x,y  ?

thanks!

Ed
