Chapter 3: Part B - Quadratic Rational Functions. Flashcards
1
Q
When the discriminant is ‘greater than zero’, how many turning points are there on a quadratic graph?
A
2 real roots. y = k intersects the graph twice.
2
Q
When the discriminant is ‘less than zero’, how many turning points are there on a quadratic graph?
A
No real roots. y = k doesn’t intersect the graph.
3
Q
When the discriminant is ‘equal to zero’, how many turning points are there on a quadratic graph?
A
One real root. There is a stationary point where y = k.
