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
