Steps How to Draw a Graph of a Quadratic Function

By : Hana Sofiyana

·       Find the x-intercept if y= 0. You can use factorization of ABC formula.

ABC formula:      Find = (x_1,0) (x_2,0)

·       Find the y-intercept if x=0.

·       Next step, find the symmetry line use y =-

·       Find the vertex 

·       Next, find some additional points, to help you fill in the graph. Click this website to find the examples. http://www.purplemath.com/modules/grphquad4.htm

·       Plot all of point on a Cartesian diagram.
