This week we learned three different formulas used to help graph. Each of these graph are important because they supply us each with different information used for plotting. To fully graph an equation its important to have all our information and by doing so we need to be able to change from one formula to another. Although we learned how to complete squares in our past units, I found this most difficult in this unit too but at the same time this concept is very important since when doing so it gives us standard form. Standard in my opinion is the best form because it gives us the vertex and line of symmetry. When in standard form, convert into other forms seems easier.
