Transformations:
If a is negative it is a reflection across x-axis
If b is negative (change of symbol of x variable) it is a reflection across the y-axis
If h is positive it is a translation h units to the left
If h is negative it is a translation h units to the right
If k is positive it is a translation k units up
If k is negative it is a translation k units down
Given expressions and corresponding transfomation are:
1.
x-variable change of symbol: Reflected across the y-axis
2.
k = +5: Translated up by 5 units
3.
h= -5: Translated right by 5 units
4.
h= +5 : Translated left 5 units
5.
a: negative: Reflected across the x-axis
6.
k: -5: Translated down by 5 units
