A power learning aid combining Coaching Calculators and Guides to help students master the solving of quadratic inequalities by sketching their associated graphs.
Coaching Calculators cover :
Solving quadratic inequalities
- by sketching associated graph
The Guide covers :
- Writing in general form
- Finding the graph shape
- Finding the x-intercept(s) if any
- Sketching the graph
- Finding the solution by inspection
Examples cover major types of quadratic inequalities and feature the finding of x-intercepts by factoring, completing the square and the quadratic formula.
The app also includes Guides and Coaching Calculators for finding the vertex of a quadratic graph :
- by completing the square
Minor bug fixes and app streamlining. Secondary modules are moving to free apps for you to GET if you wish.
