1. The document defines two sets, one with 4 elements (X={1,2,3,4}) and one with 6 elements (Y={A,B,C,D,E,F}). It defines a function f from X to Y such that f(1)=c, f(2)=b, f(3)=f, f(4)=d. 2. It asks to graphically represent the functions f(x)=x^3, f(x)=x^2+1, and f(x)=2x-1 and determine the domain and range of each. Graphs and solutions are provided in attached images. 3. It provides definitions and properties of
