Section I Part A
Directions: Solve each of the following problems, using available space for scratchwork. After
examining the form of the choices, decide which is the best of the choices given. Do not spend
too much time on any one problem. Calculators may NOT be used on this part of the exam.
In this test:
Unless otherwise specified, the domain of a function / is assumed to be the set of all real
numbers i for which f(x) is a real number.
