Task

Create a program that finds and outputs the roots of a given function, range and (if applicable) step width.

The program should identify whether the root is exact or approximate.



For this task, use:      ƒ(x)   =   x3 - 3x2 + 2x 

 
f = function(x)
{
  rval = x .^ 3 - 3 * x .^ 2 + 2 * x;
  return rval;
};
 
>> findroot(f, , [-5,5])
  0
