This comprehensive unit investigates transformations of quadratics, having learners follow "Optima" through the development and growth of her quilting business. Deftly weaving the story into the mathematical mechanics, the unit gives forms and transformations of quadratic functions a unique grounding in physical situations. Learners break down the whys and the hows of transformations, in the process developing a keen mathematical intuition for teasing information out of the function.
