# Math 116 - Final Exam Study Guide

1. Six graphs from the eight basic graphs on the front cover of the text, are shown. For each graph, identify the name of the basic graph and the equation of the graph shown. The graphs will be translated in some way.
2. Find the inverse of a function.
3. A table of x, f(x), and g(x) values is given. Use the table to find the combination of functions. Five parts.
4. Simplify an expression involving i.
5. Solve the quadratic equation by factoring.
6. Solve the quadratic equation by extraction of roots.
7. Solve the quadratic equation by completing the square.
9. Solve the equation for x. Look at the problems on the take home like those that occur in calculus.
10. Given the sketch of a polynomial function, write a function (in factored form) whose graph could be that shown.
11. Given a polynomial function, give the total number of real or complex zeros, the maximum number of positive and negative roots, the right and left hand behavior of the graph, where the graph crosses and touches the x-axis, the y-intercept, the domain, the form of any possible rational zeros, and all real and complex roots. Make a sign chart for the function.
12. Given the sketch of a rational function, write a function (in factored form) whose graph could be that shown.
13. Given a rational function, give the domain, the behavior at a point where there is a common factor between the numerator and denominator, the behavior at each vertical asymptote and x-intercept, and the horizontal asymptote. Make a sign chart for the function.
14. Find a function with the indicated zeros. Pay special attention to those involving radical or complex roots.
15. Use synthetic division to divide a polynomial by a binomial.
16. Combine several logarithms into a single logarithm.
17. Expand a single logarithm into the sum, difference, and constant multiples of several logarithms.
18. Use your calculator to approximate the logarithmic expression to three decimal places.
19. Solve the logarithmic equation.
20. Solve the equation involving exponents.
21. Find the partial fraction decomposition for the expression.
22. Solve a system of linear equations by graphing.
23. Solve a system of linear equations by substitution.
24. Solve a system of linear equations by addition or elimination.
25. Solve a system of linear equations by Gauss Jordan Elimination using matrices.
26. Solve a system of linear equations by Cramer's Rule.
27. Solve a system of linear equations by Matrix Algebra with the inverse of a matrix. You can use the calculator, but write the matrices entered into the calculator and the expression evaluated with the calculator.
28. Setup and solve a system of linear equations which will find the equation of a parabola passing through the given points. Then use your calculator (matrix inverses or RREF command) to find the solution.
29. Solve a matrix equation. Watch out for commutativity and division.
30. Multiply two matrices.
31. Find the determinant of a 3×3 matrix. The vertical lines do not mean take the absolute value.
32. Write the solution to a system of linear equations from a matrix in row echelon form.
33. Write the solution to a system of linear equations from a matrix in reduced row echelon form.
34. Write the first five terms of the sequence with the given general term.
35. Find the sum of an arithmetic series.
36. Find the sum of an infinite geometric series.
37. Simplify the ratio of the factorials.
38. Expand a binomial using the binomial expansion theorem.
39. Identify the conic section or degenerate case. Nine parts.
40. Write the equation of the conic section that is described. You do not need to graph it.
41. Eliminate the parameter from a set of parametric equations.
42. Sketch the graph of the conic section that is already in standard form.
43. Complete the square and place the conic section into standard form. Then sketch the graph.
44. Find the equation of the conic section shown.
45. Write whether or not the simplification is valid. Seventeen parts. Capital letters represent matrices and lower case letters represent real numbers. Several of these deal with inverses (when do two things inverse out?).

## Notes:

• Make sure you use the proper technique to solve the equation or systems of equations. All the systems are 2×2.
• This test is open notebook. Your old tests may be in your notebook. This study guide should certainly be in the notebook.
• Make sure your notes on the areas covered on the test are full. If your notes aren't complete, supplement.
• You may want to organize your notes. Here are some helpful suggestions based on what some people have done in the past.
• Index the sections with tabs that will be used on the test.
• Another idea would be to put all the notes for the test on at the beginning. Indexing would be better, as you may not get everything that's on the test, and then your notes would be out of order.
• Take the study guide and indicate what section of the book that applies to so they know where to go in their notes.
• Take the study guide and match up the description with problems from previous tests. Make notes like "Look at problem 4 on the chapter 5-6 test". You may find it useful to copy and paste the study guide into Word and then add line breaks so you can have more room to make notes.
• The test has been arranged so that it is is primarily in chapter order.
• Answer as many questions as you can without using your notes. You will not have adequate time to research every question in your notes.
• There is a take home test over sections 6.4-6.5 that is worth 25 points. It is due the day of the final exam.
