MATH 1113 Pre-Class Assignment Name
Section 1.1
Watch the Pre-Class videos for Section 1.1 and answer the following questions. Remember
that in your written work you are graded on the correctness of your supporting work and not
just your final answer. Always give an exact answer unless you are explicitly told to round;
calculator approximations will not receive full credit. This assignment is due Friday,
January 10, 2020 at the beginning of class.
