Question 1: describe the transformations that map the function y=2^x onto the following function: y=2^x -2 1.translate right 2 units 2.translate left 2 units 3.translate down 2 units 4.translate up 2 units

Remember that a a translation is a type of transformation in which you shift the graph of a function horizontally or vertically. Adding to the output of a function moves the graph up; whereas, subtracting from it moves the graph down. Since you are subtracting 2 to the output of the graph , you are moving the graph of  tow units up. 

Therefore, the correct answer is: 4.Translate down 2 units.
