"Show all of your work including critical numbers, like critical numbers and the number lines used to determine the answers."
(dotted line means "over" and ^ mean powered)
f(x)= 2x^2
---------
x^2-4

f '(x)= -16x
--------------
(x^2-4)^2

f "(x)= 16(3x^2 + 4)
-----------------
(x^2 - 4)^3

A) find all relative extrema.

B)Find all points of inflection.
