College Algebra Homework Assignments – Part 3
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.

For the following add-on problems, use the given constraints to graph the feasible region;
find the corner points of the feasible region; and then find the maximum and minimum values
of the objective function.
Add-on Problem 1:

constraints: 3x + 5y ≤ 177; x + 3y ≤ 99; x ≥ 0; y ≥ 0.
Add-on Problem 2:
Find the maximum and minimum values of the objective function f = 8x + 4y subject to the
constraints: 3x + y ≤ 18; y – x ≤ 3; x + 4y ≤ 17; x ≥ 0; y ≥ 0.
Add-on Problem 3:
Find the maximum value of the objective function f = 8x + 7y subject to the constraints:
x + y ≤ 9; x + y ≥ 2; x ≥ 0; y ≥ 0.
