Use the dynamic figure to check into how many pieces you can cut a cake with 4 cuts. (You want to have as many pieces as possible.)
  • Construct a function to describe the dependence of the maximum number of pieces on the number of cuts.
  • Use the figure to check the value obtained through the function you constructed for the case of 5 cuts.
  • Into how many pieces can you cut a cake with 10 cuts?
