MAC 1105 Test 3 Review 2.4 – 2.9, 3.1, 3.6, 3.8 • You will need to have your own graphing calculator for the test. • You may not share calculators or use any type of communication device in place of a calculator. • Tests cannot be made up for any reason other than an NWFSC event for which you must miss class. • If you miss one test, your final exam score will be substituted. A second missed test is a zero.
To Study for the Test • Complete all assigned homework. Remember that a score of at least 70% on each assignment gives you 10 bonus points on the test. • Complete the practice test and check your solutions. • Set up a study system (note cards for example) for each of the 20 objectives in the chart above. • Review your notes and applicable problem set questions for each of the 20 objectives in the chart above. • Work the suggested text problems for each of the 20 objectives in the chart above.
1) Give the domain and range of each relation. Indicate whether the relation is a function by writing “yes” or “no”. a) Domain: {1, 2, 3, 4, 5} Range: The relation is not a function since 1 is associated with both 3 and b) Domain: Range: The relation is a function.
3) Find the domain of each function (in interval notation). a)
4) Graph the following function in your graphing calculator and determine the intervals where the function is increasing and the intervals where the function is decreasing. Increasing: Decreasing:
10) Circle the correct answer in each case to indicate what happens to the graph at each step.
11) Write an equation for the function whose graph fits the following description. The graph of is shifted four units right, reflected in the y-axis and shifted two units up

12c) Find 12d) Find
17) The function can be used to model the height of a pumpkin launched by an air cannon after the pumpkin has traveled feet. What is the maximum height of the pumpkin (rounded to the nearest foot)?
19) Let a) Find the vertical asymptote(s) of the function. Write (not b) Find the horizontal asymptote(s) of the function. Write (Not 2)
20) The stress in the material of a pipe varies jointly with the internal pressure and internal diameter of the pipe and inversely with the thickness of the pipe. The stress is 100 pounds per square inch when the diameter is 5 inches, the thickness if 0.75 inches, and the internal pressure is 25 pounds per square inch. Find the stress when the internal pressure is 50 pounds per square inch, the diameter is six inches, and the thickness is 0.5 inch.
