Work through a model or a representation, then answer questions about it.
- Function labFreeDrag the parameters; graph, table and formula move together.Transformations of FunctionsOpen
- Rate of changeFreeSecant slopes over equal intervals, and what concavity says.Rates of ChangeOpen
- Polynomials and rationalsZeros, holes, asymptotes and end behavior from the factors.Rational Functions and HolesOpen
- Exponential and log labRatios versus differences, logs as inverses, semi-log plots.Change in Linear and Exponential FunctionsOpen
