Algebra 2· Study notes
Algebra
Functions as objects: transformations, polynomials, rational and radical functions, exponentials and logarithms, sequences and series, conics, matrices and probability.
What you'll be able to do
- Analyze and transform any parent function
- Factor and solve polynomial equations, including complex roots
- Solve exponential and logarithmic equations
- Sum arithmetic and geometric series
Read the notes as a guided lesson
Walk the notes one box at a time — prose, worked examples, quick checks — with a timed practice round after every section. For the full course with interactive lessons, go back to the course.
Every test ends with a score by topic and a list of what to revisit. Test out of a topic with 80% or better to mark it mastered.
