This unit extends our understanding of functions to include functions formed by the addition, subtraction, multiplication, and division of two functions, and from the composition of two functions. Through investigation, key characteristics and properties of these combined functions will be analyzed, and connections will be made between the algebraic, numeric, and graphical representations.
