Often we see students trying to solve quadratic inequations using algebra. This is a sure fire way to get yourself into trouble! Use this method to ensure you solve inequations correctly every time.
The Great Debate: Would this rule create a positive or negative parabola?
This often stumps my students – does the following rule create a positive or negative parabola? Whilst you are unlikely to be asked ‘is this a positive or negative parabola’, you’ll certainly need to appreciate what transformations have occurred to the basic parabola to create this new one.
