The course — 8 units, in order
01 Functions & Transformations Function notation, domain and range, the four graph moves, absolute value, and piecewise functions. Start 02 Quadratics & Complex Numbers Vertex form and completing the square, the number i, complex roots, and quadratic inequalities. Start 03 Systems & Nonlinear Models 2×2 systems at speed, three variables, curves meeting lines, and feasible regions with the corner principle. Start 04 Polynomial Functions End behavior, division and the remainder/factor theorems, zeros with multiplicity, and cubic+ equations. Start 05 Radicals & Rational Exponents Fractional powers, radical arithmetic, equations with phantom solutions, and inverse functions. Start 06 Exponentials & Logarithms Growth and decay, logs as the reverse gear, the three log laws, and solving both equation families. Start 07 Rational Functions Variation, asymptotes and holes, rational-expression arithmetic, and equations with work problems. Start 08 Sequences & Series Arithmetic ladders, geometric rockets, infinite sums, sigma notation, and recursion — the capstone. Start
