Steps for Graph Quadratic Function; Wiyarsih


Steps for Graph Quadratic Function:
1.     Quadratic function have formula ax2+bx+c
2.  Determine the function is up (U) or down (n) graph, with analysis the value of discriminant and a
3.    Find many point to make easier plot the graph
4.    Find intercept point of X1,2, where Y=0 by using Factorization or ABC formula
5.    Find intercept point of Y where X=0 ; Y=C
6.    Then find the symmetry point by using x=-b/2a
7.    After that determine the extreme point HP= (-b/2a,D/-4a)
8.    Then you can plot all off point and connect each other
9.  Please make it smooth.

Good Luck :) 
Wiyarsih
