  • How a parabola shifts and stretches
  • Reading a formula from a graph

How to play

Move the sliders for a and b (later h and k) and watch the graph change until it matches. On level 3, pick which formula draws the dashed graph; a wrong one is drawn so you can see why.

Levels

  1. Level 1Lines y = ax + b.
  2. Level 2Parabolas y = a(x − h)² + k.
  3. Level 3Which formula draws this graph?

A tip for parents

Ask your teen to show you what happens to the line when a is negative.
