| 1. Skill Building | |
A solid foundation of skills is required to succeed in Advanced Functions. This unit focuses on acquiring and mastering skills such as: dividing polynomials and factoring higher degree polynomials; multiplying and dividing rational functions; writing exponential equations in logarithmic form and applying logarithmic rules.

| 4. Solving Polynomial and Rational Functions | |
Now that students have an understanding of polynomials and rational functions, we take the next step and use the skills to solve equations and inequalities. Interval charts or number lines are introduced to solve inequalities. The skills obtained in previous units are used to algebraically manipulate polynomial and rational equations in order to solve for unknowns. The relationship between algebraic and graphical solutions is explored using graphing technology. | 10 hours (4 hrs online/ 6 hrs offline) |
| 5. Solving Trigonometric, Logarithmic and Exponential Functions | |
Students will build upon the foundational skills and learn to solve trigonometric, logarithmic and exponential functions. The periodicity of trigonometric functions is explored algebraically and graphically to find multiple solutions to trigonometric equations. Students will use their knowledge of trigonometry and solving equations to solve linear and quadratic trigonometric equations. Logarithms and logarithmic rules are applied to exponential equations to solve exactly. Logarithmic rules are also applied to logarithmic equations to create single logarithms on both sides of an equation in order to solve. | 12 hours (5 hrs online/ 7 hrs offline) |
