Transformations of Parabolas


Value of a
Value of h
Value of k
Lets try it all together!
Example 1) y= -8(x-12)^2+7
- Reflection on its x-axis
- Vertically stretched by factor
-8
- Horizontally translated 12 units
to the right
- Vertically translated 7 units up
1) 0.5(x+3)^2+15 2) y=2(x-6)^2+6 3) -0.6(x+2)^2+5
4) 10(x-6)^2+7 5) y=4(x-3)-9
[Answers are below after completing]
Answers:
1) 0.5(x+3)^2+15 2) y= 2(x-6)^2+6 3) -0.6(x+2)^2+5
- Opens up - Opens up - Reflection on its x-axis
- Vertically stretched by factor 0.5 - Vertically stretched by factor 2 - Vertically compressed by factor -0.6
- Horizontally translated to the left 3 units - Horizontally translated to the right - Horziontally translated to the left by 2 units
- Vertically translated 15 units up 6 units - Vertically translated up 5 units
- Vertically translated up 6 units
4) 10(x-6)^2+7 5) y= 4(x-3)-9
- Opens up - Opens up
- Vertically stretched by factor 10 - Vertically stretched by factor 4
- Horizontally translated to the right by 6 units - Horizontally translated to the right by 3 units
- Vertically translated up 7 units - Vertically translated down 9 units
