Functions and Change

Not started

Keep the first math path compact: read parent-curve moves first, then rational asymptotes and domain breaks, then exponential growth and decay, local slope, visible limit behavior, and finally accumulation so change stays graph-first all the way through.

Entry diagnostic

Decide where to enter this path without opening a second testing system.

Reuse the graph-transformations quick test, the rational domain-break checkpoint, and the exponential target-time quick test to decide whether to start from parent-curve moves or jump straight into local slope.

About this track

Keep the first scan focused on the next lesson. Open the authored rationale and shared-framework notes only when you need them.

Why this order

The sequence is authored to keep the model honest.

Graph Transformations comes first because it trains the eye to treat changes in an equation as visible changes on one shared graph. Rational Functions / Asymptotes and Behavior follows while that shift language is still fresh, so vertical and horizontal asymptotes stay attached to one shifted reciprocal family instead of becoming detached algebra. Exponential Change / Growth, Decay, and Logarithms then adds a second non-polynomial family while the graph-first habit is still active, so multiplicative change and inverse target time stay visual instead of symbolic. Derivative as Slope / Local Rate of Change builds on that same graph-reading habit by asking how the curve changes at one point. Limits and Continuity / Approaching a Value follows while that limiting language is already on the table, so one-sided approach, removable holes, jumps, and blow-up behavior stay attached to the same honest graph rather than turning into edge-case vocabulary. Integral as Accumulation / Area closes the path by turning local-rate and limit language into a running-total view, so slope, approach, and accumulation stay connected instead of becoming separate shelves.

Shared concept pages

Each step opens the same simulation-first framework.

Compare mode, prediction mode, quick test, worked examples, guided overlays, challenge mode, and read-next cues stay on the concept pages. The track only decides the guided order and the next recommended stop.
