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 :)
