Four connected investigations

  1. 01Functions as Change: One Input, One OutputRead a function as a dependable rule that maps an allowed input to one output.Open
  2. 02Functions as Change: Read the RateFind how much an output changes for each unit of input, then separate that rate from a starting value.Open
  3. 03Functions as Change: Build and Bound a Linear ModelConnect a linear rule to its rate and initial value, then state what a model does and does not justify.Open
  4. 04The Transformation Lab: Move the CurveShape a parabola with the parameters a, h and k until it matches a target — and learn why the horizontal shift works backwards.Open

What this path asks you to reason about

  • Evaluate a function and test whether each input has one output.
  • Distinguish rate of change from an initial value.
  • Build a simple linear prediction and state its range and assumptions.
