Second Derivative Test Example - Sketching y = x^4 - 4*x^3

[mes]

In this video I illustrate further on using the Second Derivative Test by going over a very useful example to show how you can use this test to help sketch a function by hand, noting where it is concave upwards or downwards, local max and min, and the inflection points.
