Examine the function $y = x^2 - 4x + 3$ and determine:

  • if the curve has a maximum or minimum point?
  • the function's zeroes
  • the function's line of symmetry,
  • coordinates of the turning point

    Note that you can easily factor the function into $(x-3)$ $(x-1)$. Your zeroes should be obvious from that. And, I second David Mitra's comment. Some derivatives would make this process for extrema slightly easier.2012-04-01
