This course includes the study of functions, polynomial functions, rational equations, radical equations, exponential and logarithmic equations, conics, matrices, and introduction to linear programming and non-linear systems.


Include, but not limited to:

1: Identify various functions, including square root, cubic, and piecewise-defined functions, and perform transformations and operations on known functions to create new functions. Construct mathematical models from real-world word problems.



2: Identify quadratic, polynomial, and rational functions and analyze their graphs. Solve polynomial and rational inequalities. Evaluate real-world problems using rational function models.



3: Find the real zeros of polynomial functions using various theorems.



4: Identify one-to-one functions and find their inverses. Explore exponential and logarithmic functions and use their properties to model and solve real-world problems involving compound interest and uninhibited growth/decay.



5: Explore angles and their measure. Establish the value of trigonometric functions using right triangle trigonometry. Analyze properties of the graphs of trigonometric functions and apply transformations and shifts to sinusoidal graphs.



6: Explore inverse trigonometric functions. Prove identities involving trigonometric functions and use them to solve trigonometric equations.



7: Solve real-world applications by creating right triangles and using trigonometric and inverse trigonometric functions.
