The problems here will require good familiarity with the notes on sets and functions. You'll also need to be comfortable with the material on solving equations we reviewed. A Suppose S = {1, 2, 3} and T = {a, b, c, d}. Let f be the function from S to T defined by 1 2 a 3 d Also suppose m is the mapping from S to S defined by 2 2 3 3 Write out the function f om in a table. What is the graph of f om and how does it relate to the graph of f? (Question: what set are these graphs subsets of?) B Let the function f : R - R be defined by f(x) = (x| (that is, f is the absolute value function on R). Let m : R - R be the function defined by m(x) = x + 1. The graph of f is the set of points in the Cartesian plane that are either of the form (a, a) where a 2 0, or of the form (a, -a) where a
