07 Transformations Investigation Activity 1
- Jason Lee
y = x² vs y = (x - a)² + b
Shift the slider value for a from a = 0 to a = 4. Describe the resultant transformation of y = x² to y = (x - 4)².
With the slider value of a kept at 4, shift the slider value for b from b = 0 to b = -6. Describe the resultant transformation of y = (x - 4)² to y = (x - 4)² - 6.
What are the coordinates of the turning point of the curve with equation y = (x - a)² + b?
Describe a two-step transformation from y = x² to y = x² - 8x + 8. Show your working clearly.
What is the technique you have used in Question 6.4 to work out the two-step transformation?
Describe the replacement of variable in each step of your two-step transformation in Question 6.4.
