Sketching Quadratic Graphs – Complete Lesson

This is a complete lesson on sketching quadratic graphs that looks at how to produce sketches of quadratic functions, indicating roots, intercepts and turning points. The lesson is designed with the new GCSE specification in mind.

Lesson Objectives

  • To sketch a graph of a quadratic function by factorising or using the formula, identifying roots, y-intercept and turning points.
  • To be able to identify whether the graph of a quadratic equation has any real roots.
  • To find approximate solutions to quadratic equations using a graph.
