The cubic function is one of the most frequency occurring functions. It is interesting to investigate some properties of a cubic function.

1. Consider a cubic function f(x):ax^3+b , where a and b are real number and a not equal to 0. The shape of the graph of the cubic function depends on the value on the values of a and b.

   c) Investigate the points of intersection of the graphs of f and its tangents. What can u say abt the number of point of intersection.

这个问题有 1a, 1b, 1c.. 但是都是各各的，毫无联系。

我现在的问题是，我不会画tangents出来(in the graphs)..

这个是assignment 来的。lower form6 (2012)第一课, function.

拜托，帮帮我忙 >.<
