Given the definition of a quadratic and its graph, write an accurate function definition for the rate of change. Then graph that rate of change function.
1. y = x2 - 2x - 1 ROC =
Find the location (an ordered pair) of the minimum or maximum. Also state if it is a minimum or maximum.
2. y = 2x2 + 12x – 15
3. y = x2 – 20x + 9
4. y = -3x2 – 18x + 12
5. y = -x2 + 8x – 1
