Polynomial and rational functions (content A, C, D, E)
12. Determine the domain and range of polynomial and rational functions, with and without a calculator.
13. Determine zeroes (x-intercepts), the vertex, and axis of symmetry for quadratic functions, and use this information along with the y-intercept to sketch the graph without a calculator.
14. Determine the quadratic function if given various items of information (x-intercepts and a point, or vertex and a point) with and without a calculator.
15. Sketch the graph of a polynomial, using all available information: degree, sign of the leading term, zeroes (x-intercepts), the y-intercept, and the multiplicity of repeated zeroes.
16. Determine vertical and horizontal asymptotes, zeroes (x-intercepts), open circles, and y-intercepts for rational functions and use this information along with test points to sketch the graph.
17. Solve polynomial and rational inequalities and show the solution graphically and symbolically (inequality notation, interval notation, or set notation).
Exponential and Logarithmic functions (content A, D, F)
18. Graph exponential functions and correctly interpret graphs of exponential functions.
19. Solve problems involving exponential growth and decay functions with and without a calculator.
20. Use the relationship between exponential functions and logarithms to rewrite an exponential in logarithmic form and vice versa.
21. Use properties of logarithms (exponent property, sum and difference properties) to solve exponential equations without a calculator.
Applications (content G)
22. Solve a variety of business applications including the following:
- Break-even analysis for linear revenue, cost, and profit functions
- Equilibrium points for linear or quadratic or rational demand and supply functions,
- Finding a linear cost, revenue, or profit function given information such as marginal cost, fixed cost, price per item,
- Finding maximum profit, maximum revenue, or minimum cost, for quadratic profit/revenue/cost functions.
23. Solve a variety of application problems using rational, polynomial, logarithmic, and exponential equations and inequalities involving business, and topics chosen from health, social and natural sciences.
Matrices (content G)
24. Use row operations and the Gauss-Jordan Method to solve linear systems.
25. Perform basic matrix operations to include adding, subtracting, and multiplying matrices with and without a calculator.
Linear Programming (content H)
26. Optimize the objective function, consider constraints, and use graphical techniques.
27. Set up linear programming problems (objective functions and constraint inequalities) from applications.
Set Operations (content J)
28. Determine the complement, intersection, and union of two or more sets.
29. Use Venn diagrams to solve application problems involving business, health, social and natural sciences data.
Finance (content K)
30. Use finance formulas to compute future value, present value, and compound interest (including annually, quarterly, weekly, and daily).
31. Compute future value, present value, simple interest, compound interest (including annually, quarterly, weekly, and daily), continuous interest, and amortization schedules for a variety of finance problems.
Writing
