The Problem marker indicates problems for mastery of the current material and problems introducing new material. Each chapter starts with a brief discussion of the application or history of the content material. Each section within a chapter starts with a brief introduction to the new material, followed immediately by a problem or an example.
Problems provide the students an opportunity to find the focus, vertex and directrix of parabolas.
A demonstration then shows how parabolas are translated on the coordinate plane. Each section ends with problems for practice with the material presented in the section. At the end of each chapter are problems for review of the entire chapter. ENC does NOT distribute this resource.
