College Algebra Homework Assignments – Part 1
General Directions
Show all work. The more work you show me, the more partial credit I can give you. Graph manually unless you
are specifically told to graph with a calculator. With every graph, include a t-chart with 5 “key” points (minima,
maxima, inflection points, x-intercepts, y-intercepts). For an oblique line, you may give three points – the xintercept, the y-intercept, and one additional point. Give domains and ranges in interval notation. Unless
otherwise directed, round answers to 3 decimal places. Always check your answers against the back of your
textbook (for odds) or the instructor’s book (for evens). Cycle-back problems are NOT optional.
