Vertical stretch/shrink | when a function is multiplied by a constant "a" if "a" is between 0 and 1, it is a vertical shrink (or compression). If "a" is greater than 1, its a vertical stretch. Both factor of "a". |
Horizontal stretch/shrink | when a function's input is multiplied by a constant, "b" if "b" is between 0 and 1, there is horizontal stretch by a factor of 1/b. if "b" is greater 1, there is a horizontal shrink (or compression) by a factor of 1/b |
Horizontal translation left/right | when a constant is added to or subtracted from a function's input. adding a constant= translation left, subtracting a constant=translation right. |
Vertical translation up/down | when a constant is added to or subtracted from a function. Adding=translation up; subtracting=translation down |
Reflection across y-axis | occurs when a function INPUT is multiplied by a negative coefficient |
Reflection across x-axis | occurs when a function is multiplied by a negative coefficient. |
