This is an amazing site if you need help with linear comparisons and linear equalities and inequalities. I learned about graph transformation operations which change a function by changing it's graph. There can be one function or more than one function, the site calls it a family function. The site described the 10 parts of quadratic functions and then explained each of the 10 in detail. There was an exercise on how to write an essay on transformations which I didn't do but I looked at the steps and it seemed very applicable. For example,it gavefeatures of quadratic equations like symmetry, intersections with the axes, and vertexes. I liked learning about linear and non linear comparisons since that is what we are studying in math class right now.
This site is set up really clever. There is a total of 10 parts to the quadratic functions. Within each part there are sets of activities tools, tasks and exercises that help navigate you around the site. At the bottom of each page there is a suggested activity that can help you apply what you have learned. It is either in the form of writting a report or writing an essay. I think out of all the sites I have visited so far, this one looks like it would be most helpful to students and teachers.
Time spent reviewing site: I spent about 30- 40 minutes looking at the site. I enjoyed looking at the polynomial forms and the addition to functions.
