Topic 4: Building New Functions
After completing the topic Building new functions, students will be able to : build polynomial functions from linear and quadratic functions build rational expressions from polynomial expressions perform operations on rational expressions define rational functions use interval notation to describe a part of a graph learn about the rate of change and concavity of polynomial functions
3
Topic #4: Word Wall Words
polynomial expression, polynomial function, rational expression, rational function, local maximum, local minimum, increasing function, decreasing function, concavity, inflection point interval notation.
4
Drill Simplify the following expressions. Factor the following polynomials. (Make a factor/sum table if you don’t know the factors)

6
Drill Write each of the following using set notation, interval notation and as a graph.
7
Drill Using the graph on the chalkboard, identify the following intervals: 1.) Increasing, decreasing, 2.) concave up, concave down, and 3.) points of inflection and end behavior. What degree (even or odd) is this function? What is the value of the leading coefficient?
