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
