INTRODUCTION

This unit deals with graphs of second degree polynomial (quadratic) functions . It starts by looking at the simplest graph, y = x2,  and focuses on different types of quadratic functions, relating them back to this initial example by using translations.

AIMS
  • Know what the graph of a quadratic function is like from looking at its algebraic equation.
  • Discover similarities and differences between the graphs of different quadratic functions by looking at their coefficients.
