  • Identify the graphs of power functions in the form of y = axn for values of n=0,1,2,3,-1,-2
  • Sketch the graphs of power functions.
  • Describe the graphs of power functions.

Check that you have achieved the above at the end of the lesson.

Explore using Desmos

Instructions:

  • Copy and complete the table shown on the side.
  • For each graph, plot it in desmos to see its appearance.
  • Sketch the graph in your book.
