Functions
Graph, trace, solve and interpret functions and models. Every guide is scoped to the current AA SL course.
Graph a function
You need to see one or more functions on the graph screen.
Open guideWindow & zoom
A graph is blank, clipped, flattened or misleading.
Open guideTrace & evaluate
You need a coordinate from a graph or the value of a stored function.
Open guideValue table
You need repeated function values or your table starts at the wrong place.
Open guideFind zeros
You need an x-intercept or a numerical solution of f(x)=0.
Open guideFind intersections
You need a solution of f(x)=g(x) or the crossing point of two models.
Open guideMaxima & minima
You need a turning point or stationary value numerically.
Open guideDomain, range & asymptotes
You need graphical evidence for allowed inputs, outputs, holes or asymptotic behavior.
Open guideTransformations & inverses
You want to compare related functions or check inverse/composite behavior numerically.
Open guidePiecewise functions
A function has different rules over different intervals.
Open guideRegression in functions
Data suggest a linear, quadratic or exponential model that you need to graph or use for prediction.
