Variable a
What are rules to remember for variable "a"
Vertical Stretch
Vertical Compression
Reflection of the x - axis
What are rules to remember for variable "h"
Horizontal shifts to the left and right
Positive but looks negative
Negative but looks positive
What are rules to remember for variable "k"
Vertically shifts up and Vertically shifts down
When would "a" be vertically stretched?
if a is greater than one(a>1), then y=x2 is vertically stretched by a factor of "a"
When would "h" be horizontally translated to the left
if h < 0 (negative, but looks positive), y=x2 is horizontally shifted to the left
When would "k" be vertically translated up
if k>0 (positive) y=x2 is vertically translated up
When would "a" be vertically compressed?
If 0<a<1 (if a is between zero and one) then y=x2 is vertically compressed
When would "h' be horizontally translated to the right
If h>0 (positive but looks negative) horizontally translated to the right
When would "k" be vertically translated down
if k<0 (negative) y=x2 is vertically translated down
When would "a" be reflected in the x-axis
If a<0 (less than 0(negative) then y=x2 is reflected on the x-axis
is y=-2(x-1)2-3 horizontally translated to the left or right
Horizontal translated 1 unit right
is y=-2(x-1)2-3 translated up or down
its vertically translated 3 units down
Is y=-2(x-1)2-3 stretched, reflected or compressed?
it is stretched by a factor of 2
is y=-4(x+4)2-5 horizontally translated left or right
Horizontally translated 4 unit left
is y=-5(x-2)2+4 translated up or down
is vertically translated 4 units up
