  1. The other day, we saw that a quadratic equation can have 0, 1, or 2 solutions. Sketch the graph that represents the quadratic function: one that has no zeros. (.ggb)
     
  2. Sketch the graph that represent the quadratic function: one with 1 zeros. (.ggb)
     
  3. Sketch the graph that represent the quadratic function: one with 2 zeros. (.ggb)
     
  4. Use graphing technology to graph the function defined by f(x)=x²-2x+1. (.ggb)
     
  5. Graph it to check your prediction. (.ggb)
