Quadratic Graphs

Quadratics

  • Quadratic equations contain an x^2 term
  • Quadratic equations have curved graphs
  • You can draw the graph of a quadratic equation by completing a table of values

Drawing quadratic curves

  • Use a sharp pencil
  • Plot the points carefully
  • Draw a smooth curve that passes through every point
  • Label your graph
  • Shape of graph will be either u or n
  • Drawing a smooth curve
    • It’s easier to draw a smooth curve if you turn your graph paper so your hand is inside the curve
  • Check it
    • All the points on your graph should lie on the curve
    • If one of the points doesn’t fit then double check your calculations
