Let's Review Translations:
•A vertical translation moves an exponential function up or down. •When we add to our equation, the graph moves UP. y = abx + a number •When we subtract from our equation, the graph moves DOWN. y = abx - a number
Remember that a Number added or subtracted outside the exponent moves the graph up or down!!
•When we have a horizontal translation, we are adding to or subtracting from the exponent.
Add - Moves Left Subtract - Moves Right
Number outside moves (+) or down (-)
Number in exponent moves left (+) or right (-)
