Take a look in the window. Pupils watch a presentation to discover how to graph a polynomial using a graphing calculator and using the window to find the extrema. Scholars use their knowledge from previous lessons to gain a rough idea of how the graph behaves before using the worksheets to practice graphing polynomials.

Concepts
