Exponential & Logarithmic Functions (Book 4.0)

Book 4 of The Calculus Bridge. Some things grow by adding; others grow by multiplying. Learn the functions behind compound growth and decay — and the operation that undoes them.

Three short chapters:

• Growth and Decay: f(x) = a·bˣ — the starting value, the growth factor, and the horizontal asymptote the curve never reaches.
• Logarithms: Undoing the Exponential: a logarithm is just an exponent. Convert between forms, and see why you can never take the log of a negative.
• The Log Rules: product, quotient and power rules, and how to solve any equation with the unknown stuck in an exponent.

Inside: a "Choose Your Move" checklist, a 20-problem practice set with full worked answers, and two short checkpoints — one before you read, one after — so you can see your own progress. Includes a page for parents and a page for teachers with standards notes.
