This video will show you the easiest way to plot a graph using the given Quadratic Function. As shown in the video, steps that needs to be taken are as follows :

  • Identifying the shape of the graph by taking into consideration the value of x^2
  • Finding the vertex (-b/2a, f(-b/2a)) where -b/2a is also the axis of symmetry
  • Finding the X-intercepts (X , 0) or (X1 , 0) & (X2 , 0) which is fondly known as roots of the function/equation
  • Finding the Y-intercepts (0,Y)

NOTE : TO SOLVE THIS TYPE OF QUESTION, YOU ARE ENCOURAGED TO UTILISE ALL THE METHOD LEARNED FROM CHAPTER I, II & III
