Question 683998: three different ways to graph the quadratic relation, . The three ways include: using a table of values, using x-intercepts, and using the vertex and step pattern.
Which method do you like the best to graph ? Why?
Answer by rapaljer(4671)   (Show Source):
You can put this solution on YOUR website! My LEAST favorite way is the table of values. I prefer the vertex method using x=-b/2a. Of course, the x-intercepts method is also nice, and also knowing that the vertex is always exactly HALFWAY beteen the two intercepts. Of course, the problem may not have x-intercepts. The vertex, where x=-b/2a, always works.
