Hi guys... So looking for some opinions. I just started teaching quadratic functions to my class. I teach at an alternative high school, and the class I am teaching this in is a graphing class. I started teaching quadratics functions and graphing them - what is the vertex, finding the vertex using -b/2a and then graphing by making a table. Students are struggling to grasp the whole concept. Anyone have any tricks for teaching this? We haven't gotten into factoring, roots, anything like that yet because I want them to get the whole table thing first.. Thanks!
