Functions That Model the World
You go deeper into functions -- lines, parabolas, polynomials, rational, exponential and logarithmic -- and learn to change, combine and solve with them, so you can describe real situations. Claude Code checks every step with you.
Class 1Linear functions and slope
Straight-line functions, and what their slope tells you.
Class 2Transformations of functions
Shifting, flipping and stretching a graph.
Class 3Combining functions and inverses
Putting functions together, and undoing them.
Class 4Quadratic functions and parabolas
The U-shaped graph and where its top or bottom is.
Class 5Polynomial functions
Graphs of higher powers, and how they behave.
Class 6Dividing polynomials and finding zeros
Splitting a polynomial to find where it equals zero.
Class 7Rational functions
Functions that are one polynomial over another.
Class 8Exponential functions
Growth and decay that speeds up as it goes.
Class 9Logarithmic functions
The inverse of an exponential, and what it answers.
Class 10Log rules and solving equations
The rules that make logs useful, and solving with them.
Class 11Systems of equations
Solving two equations that must both be true.
Class 12Final review: modeling with functions
Using everything to describe and solve real problems.
